Out of the 64 codons found in our biological system, the first was experimentally deciphered by Marshall Nirenberg and Heinrich Matthaei.
<h3>What is genetic code discovery of codons?</h3>
- The key to unlocking the genetic code was discovered when they conducted an experiment using a strand of synthetic RNA with numerous uracil units to tell a chain of amino acids to add phenylalanine.
- In 1961, Francis Crick, Sydney Brenner, Leslie Barnett, and Richard Watts-Tobin made the initial discovery that a single amino acid can be encoded by three nucleotides in DNA [7]. Scientists made the discovery of the life's code in that instant.
- Friedrich Miescher isolated "nuclein," which is DNA with associated proteins, from cell nuclei. He was the first to identify DNA as a special molecule.
- The twenty amino acids that make up protein are arranged according to a code that is formed by the four bases of DNA, which at first glance appear to be randomly arranged. Watson and Crick were the first to realize this.

Answer:
<u> Speech about "Public And Private Transport"</u>
Nowadays people from all over the world are suffering from air pollution. One of the reasons for such a situation is the constantly increasing car usage. Are we able to do something in order to encourage people not to use private cars or to use them less? To be honest, there are only several things we can do. Among them is propaganda of the risks caused by private car usage. We can provide people with the main benefits they can get by using public transport and make the transportation prices more affordable.
First of all, advertisement is a very powerful “weapon”. Many people can remember the ad they saw several years ago. Advertisement has a very strong effect. It can impress people, influence their thoughts and even change them. Of course, it is impossible to encourage all people from all over the world to use public transport only. But still, a certain number of people will definitely give up using cars and will give preferences to the public transport as time goes by.
Moreover, we can also provide people with the benefits they can get from the usage of public transport. For example, it is possible to provide those people who use public transport with a 20% discount when they need to buy something. Also, it is possible to implement special cards that will be some kind of an opportunity to change bus to train for free.
As a final point, let’s take a look at one more thing we can provide people with in order to encourage them to use public transport. It would be advisable to make the public transportation prices lower. Let’s suppose that you pay 40$ per month to drive your own car. If you give preference to public transport, it will cost 20$ per month. What would you pick as the method of transportation? Sorry to say that it may be quite hard to set the price of 20$ for public transport, as transportation companies may be against such fee’s reduction. But if it happens one day, a great number of people would give up their cars and prefer public transport in order to prevent congestion and air pollution.
I’m 100% sure that all the ways we’ve mentioned above are still really good methods to encourage people to use public transport instead of private cars.

Answer:
This lesson deals primarily with diction and tone and how to recognize them in your reading. Diction and tone are stylistic devices a writer uses to help a reader or listener “hear” what the writer is trying to say. Tone describes the author’s attitude toward the material, the audience, or both. According to Cliff’s Advanced Placement English Language and Composition Examination Preparation Guide, tone is similar to mood and is easier to determine in spoken language than in written language. Some words used to describe tone are playful, serious, businesslike, sarcastic, humorous, formal, ornate, and somber.
Tone is largely determined by diction or the word choices a writer makes. The process of choosing the right word involves denotation and connotation, which we will also discuss in this lesson.
Sometimes the tone is very clear, for example, when someone is obviously angry or distressed. To indicate these emotions, the writer might include words like “screaming” or “sobbing” and use exclamation points. Sometimes the tone is more subtle, though, and requires you to read closely in order to fully understand what is happening.
