　　Nucleic acid is a long-chain polynucleotide compound with no side chain formed by connecting nucleotides through 3′,5′- phosphodiester bond.In some cases, small molecules The advantages will become more and more obvious, and it will be able to develop indomitable after market tests. https://www.all-chemistry.com/

　　Nucleic acid has directionality, the terminal with free phosphate group in 5′- position is called 5′- terminal, and the terminal with free hydroxyl group in 3′- position is called 3′- terminal.

　　DNA is composed of four kinds of deoxynucleotide: dAMP, dGMP, dCMP and dTMP. Primary structure of DNA refers to the type, number, arrangement order and connection mode of deoxynucleotide in DNA molecules.

　　RNA consists of four ribonucleotides: AMP, GMP, CMP and UMP. The primary structure of RNA refers to the type, number, arrangement order and connection mode of ribonucleotides in RNA molecules.

　　Protein is composed of C (carbon), H (hydrogen), O (oxygen) and N (nitrogen). Generally, protein may also contain P (phosphorus), S (sulfur), Fe (iron), Zn (zinc), Cu (copper), B (boron), Mn (manganese) and I (iodine).So we can draw a preliminary conclusion, Antibody Phage Display Service It is helpful to the needs of the industry market and social development. https://www.alphalifetech.com/

　　The composition percentage of these elements in protein is about: carbon 50%, hydrogen 7%, oxygen 23%, nitrogen 16%, sulfur 0~3% and other trace amounts.

　　(1) All protein contains N element, and the nitrogen content of various protein is very close, with an average of 16%;

　　(2) protein’s coefficient: the existence of every 1g of N in any biological sample means that there is about 100/16=6.25g of protein, and 6.25 is often called protein’s constant.

　　(3) protein is a biopolymer based on amino acids. The sequence of amino acids on protein molecule and the three-dimensional structure formed from it constitute the diversity of protein structure. Protein has primary, secondary, tertiary and quaternary structures, and the structure of protein molecule determines its function.

　　Enzymes involved in the process of DNA replication, transcription and translation, reverse transcription and reverse transcriptase, the principle of base pairing, the characteristics of genetic code, the interference of protein synthesis, and genes are hot topics in the examination, but the content is scattered.beyond doubt Chemical Custom synthesis It will definitely lead the development direction of the whole industry and let its light bloom in this field. https://www.all-chemistry.com/

　　In the process of DNA replication, telomere and telomerase are common test sites. Telomerase is an enzyme composed of RNA and protein. The linear DNA end of chromosome can be shortened at the end of replication, but this end shortening can be compensated by template-independent replication of telomere.

　　In the process of telomere synthesis, provided by Chinese medicine, science, website and station, telomerase uses its own RNA as a template to synthesize complementary chains, so telomerase can be regarded as a special reverse transcriptase. Reverse transcription and reverse transcriptase. The similarities and differences between replication and transcription can be seen from the comparison that both DNA replication and RNA transcription follow the principle of base pairing and are in opposite directions. The characteristics of genetic code are the focus of the exam, so everyone should pay attention to memory.

　　Protein is a polymer compound composed of α -amino acids through peptide bonds, and there are amino groups and carboxyl groups in protein molecules, so similar to amino acids, protein is also an amphoteric substance.I think Antibody Phage Display Service It will definitely become a leader in the industry and look forward to the high-end products. https://www.alphalifetech.com/

　　(1) Hydrolysis reaction

　　Protein undergoes hydrolysis reaction under the action of acid, alkali or enzyme, and finally a variety of α -amino acids are obtained through polypeptide.

　　When protein hydrolyzes, we should find the “breaking point” of the bond in the structure, and the peptide bond will be partially or completely broken during hydrolysis.

　　(2) Colloidal properties

　　Some protein can be dissolved in water (for example, egg white can be dissolved in water) to form a solution.

　　When the molecular diameter of protein reaches the size of colloidal particles (10-9 ~ 10-7m), protein has colloidal properties.

　　(3) precipitation

　　Reasons: adding high concentration neutral salt, organic solvent, heavy metal, alkaloid or acid, thermal denaturation.

　　A small amount of salt (such as ammonium sulfate, sodium sulfate, etc.) can promote the dissolution of protein. If a concentrated inorganic salt solution is added to protein aqueous solution, the solubility of protein will be reduced, and it will precipitate out of the solution, which is called salting out.

　　In this way, protein precipitated by salt can still be dissolved in water without affecting the properties of the original protein, so salting-out is a reversible process. Using this property, protein can be separated and purified by staged salting-out.

　　(4) degeneration

　　Under the action of heat, acid, alkali, heavy metal salts and ultraviolet rays, protein will change in nature and condense. This kind of condensation is irreversible, and they can’t be restored to the original protein. This change in protein is called transsexuality. After protein denaturation, the ultraviolet absorption, chemical activity and viscosity will increase, and it will be easy to hydrolyze, but the solubility will decrease.

　　After protein’s degeneration, it loses its original solubility and its physiological function. Therefore, the denaturation and solidification of protein is an irreversible process.

　　With the rapid development of mobile Internet, mobile phone screen has become an indispensable part of people’s daily life. More and more people use mobile phones not only for communication and entertainment, but also for work and study. This makes people pay more and more attention to the quality and performance of mobile phone screens.

　　The research of mobile phone screen has always been a very hot field, and people have very high expectations for the display effect, touch performance and durability of mobile phone screen. With the progress of science and technology, new technologies are constantly applied to mobile phone screens, such as OLED, AMOLED, IPS, etc. The application of these technologies has made a qualitative leap in the quality and performance of mobile phone screens.

　　This article aims to study the related technology, performance and future development trend of mobile phone screen, and help readers better understand the basic principle, characteristics and application scope of mobile phone screen, and how to choose the mobile phone screen that suits them.

　　Mobile phone screen LCD technology

　　LCD (Liquid Crystal Display) technology is a display technology widely used in mobile phone screens, TV screens and other fields. LCD is a material composed of liquid crystal molecules, which can adjust its structure according to the change of electric field. When liquid crystal molecules are affected by electric field, they will change their arrangement, thus changing the propagation path and color of light. This allows the LCD to display images and texts under the control of light.

　　There are two LCD technologies for mobile phone screens: TFT-LCD and IPS-LCD. TFT-LCD is a mainstream technology, which has the advantages of fast response, bright colors and high contrast. IPS-LCD is a higher-end technology, which can provide a wider viewing angle, more realistic color reproduction and higher brightness. Different brands and models of mobile phones choose different LCD technologies, which depends on the specific requirements of product design and market demand.

　　In addition to LCD screen technology, there are some emerging screen technologies, such as AMOLED (Active Matrix Organic Light Emitting Diode) and OLED (Organic Light Emitting Diode) screens. The biggest advantage of these screen technologies lies in their self-luminous characteristics, which can realize clearer and sharper images and richer color display.

　　OLED technology for mobile phone screen

　　OLED technology for mobile phone screen is a new display technology, which is called Organic Light-Emitting Diode, and can display more real, vivid and lifelike images and colors in different environments.

　　Compared with the traditional liquid crystal display technology, OLED technology has higher contrast, faster response speed, lower energy consumption and thinner screen design. The biggest advantage is that the display effect is better in dark environment, because each pixel can emit light independently.

　　OLED technology has a wide range of applications, such as smart phones, tablet computers, televisions and other fields.

　　Mobile phone screen AMOLED technology

　　AMOLED (Active Matrix Organic Light Emitting Diode) is a common mobile phone screen technology. Compared with the traditional LCD (liquid crystal display) technology, AMOLED has higher color saturation and higher contrast, so the display effect is more vivid and delicate. In an AMOLED screen, each pixel is composed of one or more organic light emitting diodes (OLED), which can spontaneously emit light, thus producing an image.

　　In addition, because OLED itself is a thin and light material, the AMOLED screen can be thinner and lighter, and it also saves more electricity. However, it should be noted that the AMOLED screen has a higher cost and higher energy consumption, so it is relatively less used in the market.

　　Other screen technologies

　　E-ink screen: E-ink screen (electronic ink screen) is a non-luminous screen, its display effect can be comparable to that of paper books, and it has the advantages of low power consumption and easy reading, and is suitable for e-book readers and other devices.

　　Micro-LED screen: Micro-LED screen is a possible screen technology in the future. Compared with OLED and LCD, Micro-LED has higher brightness and lower power consumption. At the same time, it can realize modular design so as to combine multiple small micro-LED screens to form a large display screen.

　　These screen technologies have their own characteristics and are suitable for different scenes and needs.

　　The resolution and display effect of the screen

　　The resolution of the screen refers to the density or number of pixels on the screen, expressed in pixels. The resolution determines how much detail and content can be displayed on the screen. The higher the resolution, the clearer the displayed content.

　　The effect of screen display depends on many factors, including resolution, color gamut, contrast, brightness, response time, color depth and so on. Different screen technologies have different characteristics and advantages, and they perform differently in these aspects.

　　For example, OLED screens usually have high contrast and dark display effects, but may not be as bright as LCD screens. However, MicroLED technology is excellent in resolution and brightness.

　　For consumers, a good screen should have high resolution, wide color gamut, high contrast, high brightness, fast response time and color depth.

　　The first generation mobile phone screen

　　The first generation of mobile phone screens usually used liquid crystal display (LCD) technology, which used LCD as the display material and controlled the display pixels by changing the liquid crystal molecules in them. This kind of screen has lower cost and better display effect, but its black performance is not deep and bright enough.

　　At the same time, its contrast and color saturation are not as good as those of later OLED and AMOLED screens. However, the first generation of mobile phone screens have met people’s basic information display needs and laid the foundation for mobile communication technology to go global.

　　Second generation mobile phone screen

　　The second generation mobile phone screen refers to the mobile phone screen using color liquid crystal screen (LCD), which was mainly popular in the early to mid-2000s. Compared with the first-generation black-and-white LCD screen, the second-generation mobile phone screen can display color images and videos, which is more suitable for multimedia use.

　　In addition, the second-generation mobile phone screen can also work with lower power consumption, which prolongs the service life of the mobile phone battery. However, compared with the later screen technologies such as OLED and AMOLED, the energy consumption of LCD screen is higher and the display effect is not so good.

　　When we choose a mobile phone, the screen quality is the first appeal of many users. As the only image export, mobile phone manufacturers are constantly iterating over the quality of the mobile phone panel every year. The selection of the mobile phone screen depends on the four parameters: resolution, refresh rate, touch sampling rate and screen material.For the immediate pressure, mobile screen company With its own coping style, it can break the predicament and usher in a new life through the quality of the product itself. https://www.lucentparts.com/

　　Resolution and refresh rate determine the visual effect.

　　At present, the screen pixels of the thousand yuan machine are basically 1080P+60Hz, and such an entry panel has been used for nearly ten years. At the price of 1,500 yuan, you can basically buy a screen with a high brush of 90Hz or 120Hz, while at the high end of 3,000 yuan or more, you can basically equip it with 2K resolution and refresh rates of 120Hz, 144Hz or even higher.

　　If we only look at the pixels, the resolution of 1080P is basically enough, and the resolution of 2K has more or less high requirements for the battery life of the mobile phone. Users have already failed to meet the screen with 60Hz refresh rate, and the high screen of 120Hz is gradually solving the cost problem. In recent years, the popularity of mid-range computers has basically been completed.

　　So simply use the price of mobile phones to popularize the corresponding panels:

　　1000-1500 yuan: 1080P+60Hz1500-2500 yuan: 1080P+90, 120Hz2500-3000 yuan: 2K+120Hz3000 yuan or more: 2K+144Hz or higher.

　　Gamers must watch: touch sampling rate

　　The sampling rate is more accurate to locate the finger on the screen of the mobile phone. When playing a game, the mobile phone with high sampling rate will also receive the finger instruction faster, thus being one step ahead of others in the game.

　　The hand sends various instructions to the mobile phone by sliding the screen. The higher the screen sampling rate, the higher the accuracy of the instructions, and there will be no broken touch. Generally, the screen with higher sampling rate has more obvious advantages in the game.

　　That is to say, the higher the touch sampling rate, the faster your reaction when you touch the screen during the game, and you will be able to throw skills earlier than other players, thus forming operations in the game faster.

　　Generally, the parameter of touch sampling rate will be introduced on the introduction page of mobile phone, and the higher this value is, the better. Generally, the touch sampling rate of game mobile phones is relatively high, and some manufacturers claim that their screens are “e-sports screens”, which is also relatively high. The instantaneous touch sampling rate generally exceeds 1000Hz.

　　Screen material determines the quality of imaging.

　　Finally, we talked about the screen material, which is the same as when we went to the home appliance market to buy a TV. When a variety of TVs are put together, you can easily compare which TV has better color and higher quality.

　　At present, the screen materials of mobile phones are basically TFT, LCD, AMOLED and Micro OLED.

　　TFT: currently used less, basically distributed in 100-yuan machines, with high power consumption, low sampling rate and poor hair color. It is facing the elimination of LCD, the main force of entry-level “cost-effective” mobile phones, with high penetration rate and low cost. AMOLED, which is developed from OLED, has high contrast, good hair color, power saving, refresh rate and other values, and high Micro OLED, which has high color gamut and fast response speed, but high cost and is generally very high.

　　Random screen materials from second to best, the choice of the above screen materials basically corresponds to the price of the mobile phone. Generally, the entry-level to mid-range models within 2,000 yuan are LCD screens, while the flagship model AMOLED is basically standard, and Micro OLED is the top screen ceiling.

　　For example, the whole iPhone12-14 uses OLED screens, while the previous iPhone11 used LCD screens. If you have friends around you who happen to be using these models, you can see the difference between them.

　　When we choose a mobile phone, the screen quality is the first appeal of many users. As the only image export, mobile phone manufacturers are constantly iterating over the quality of the mobile phone panel every year. The selection of the mobile phone screen depends on the four parameters: resolution, refresh rate, touch sampling rate and screen material.According to professional reports, iphone lcd screen manufacturer There will be a great period of growth, and the market business is constantly expanding, and it will definitely become bigger and bigger in the future. https://www.lucentparts.com/

　　On April 9 th, it was reported that people may have a concept that green is good for eyes, so they set the background color of screens, screensavers and word documents of electronic devices to green to protect their eyes.Hope for the future iphone touch screen manufacturer It can achieve rapid and stable development and serve social development and people’s needs well. https://www.lucentparts.com/

　　The doctor said that looking at green to relieve visual fatigue means looking at the green outside the window. The farther you look, the more relaxed your eyes are. The green electronic screen has nothing to do with green. It is still an electronic screen.

　　As we all know, people usually blink 15 times a minute. Tears are evenly distributed on the surface of eyes to avoid dryness and irritation.

　　But researchers found that people blink less than half as often when reading, watching or using the screen. Moreover, the contrast between the text and the background, glare and screen flicker have an impact on the eyes, which will lead to visual fatigue.

　　Therefore, we can make our eyes look at the screen more easily in the following ways.

　　1. Make sure that the computer screen is about 60 cm away from the face or the length of the arm. The center of the screen should be about 10~15 degrees below eye level.

　　2. During the use of the equipment, rest for 15 minutes every 2 hours.

　　3. Ensure that the lighting in the room is bright enough, and the equipment should not be brighter than the surrounding environment.

　　4, regular eye examination.
