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.

The Outsiders - Chapter 11
IceJOKER [234]

Answer:

Chapter Eleven

1. True or false? Bob’s parents are partly responsible for their son’s death. Explain your answer.

Randy and Ponyboy have commented that Bob’s parents were too lenient with their son, which made him act out in worse and worse ways. In this chapter, Ponyboy wonders if Bob’s parents loved him too much or too little. Over-indulgence is equated with neglect here, making us think that Bob and Johnny had more in common than it would seem at first glance.

2. Ponyboy compares Bob to several of the members of the Greaser gang, noting Bob’s smile was like Sodapop’s, his eyes might have been like Johnny’s, and his recklessness and hot-temper were certainly like Dally’s. What is Hinton’s point in drawing such clear connections between Bob and the Greasers?

Answer - Again, Hinton is emphasizing the idea that these boys have much more in common than they realize. They are all individuals and contain far more sides/complexities than any label can accurately portray. The foolishness of their hatred is emphasized here.

3. Why, do you suppose, would Ponyboy rather have someone’s hate than his/her pity?

Answer =- Playing the victim is not Ponyboy’s style. He’d rather be hated and still hold some power than to be emasculated by pity.

4. Ponyboy has been a thoughtful voice of reason as the narrator of the story, but at the end of this chapter he’s changed and is now what is called an “unreliable narrator.” What’s going on with Ponyboy here in the last few pages of the chapter?

Answer - Put on your psychologist’s hat as you answer this question. In his deep grief over Johnny’s death, his mind has slipped into the defense mechanism of denial. He isn’t able yet to fully face the events of the last few days, so he’s lying to himself to try to ease his pain. This is interesting when we look at his statement in the first chapter, when he said, “I lie to myself all the time. But I never believe me.” On some level, Ponyboy knows that Johnny really is dead and that Johnny was, indeed, the one who stabbed Bob. He’s just not ready to deal with everything.

5. What’s another piece of evidence at the very end of the chapter that Darry and Ponyboy have repaired their relationship?

Answer - Darry is care-taking Ponyboy and calls him “little buddy,” a loving term Darry previously used only with Sodapop. Aww.

Read the following excerpt from Sandra Cisneros’s story "Mericans."
kenny6666 [7]

The statement that describes the irony in the narrator's observation that the couple is "not from here" is "the narrator is not from 'here' either," option A.

<h3>What is irony?</h3>

Irony is usually described as a situation where the consequences or outcome is different from what we initially expected. Here, however, we are looking for the irony found in the narrator's words in the story "Mericans."

In this case, the irony is not about the situation or its outcome per se. It relates more to who is saying what about whom. The girl who narrates the story is "not from here," which means she is not completely American. She is of Mexican origin, but she still judges the couple she sees by saying they were clearly "not from here."

In other words, the irony is that everyone is "not from here" to someone. The narrator is "not from here" in the sense that she is Mexican. The couple is "not from here" in the sense that they are not Catholics.

With the information above in mind, we can choose option A as the correct answer.

What clues does the title reveal about the story
ira [324]
A title can reveal many things about a story. A title may suggest a main idea or theme for text, or show some insight to a character that will be spoken about in the story. It could also introduce a symbol that the writing may follow or represent. A title is very influential to the reader because it it the first thing that they see, and it gives the first bit of information about what they will be reading. Some titles may have an entirely different meaning before you read a text versus after you read the text; therefore, it is important to analyze the title before and after reading a piece of writing.

I hope this helps! :)
