Write the molecule, functional group or class of molecules described by each clue. If the clue describes more than one (type of) molecule, give an example of a molecule or class of molecules described by the clue:
(A) Molecule used to “read” mRNA in protein synthesis. This molecule also serves as the leaving group in peptide bond formation
A. This molecule is tRNA or transfer RNA that is used to read the Codon present in mRNA by the anticodon present in it. tRNA is a type of RNA. So, it is a nucleotide, having ribose sugar, phosphate group and nitrogenous bases. Free tRNA is also the leaving group that exit from the E site present in the ribosomes.

why?
3. Which of the following statements is CORRECT? A. Exposure of E.coli to UV light greatly increases the frequency of cytosine deamination B. Mutagens that intercalate into the double helix lead to the formation of thymine dimers. C) Oxidative damage to DNA usually leads to the formation of frameshift mutations. D. Some alkylating agents are mutagenic because they chemically modify amino acids in the active site of DNA...

I only need answer to 4
4- Which is stronger - the bond between water molecules or the bond between the two amino acids (formed from the dehydration synthesis above)? Explain why? (2pt) Imagine a biochemistry lab is testing out a new procedure to improve the synthesis of a dipeptide molecule made with the amino acids Valine and Threonine. The hypothesis is that acid as a catalyst will improve the condensation reaction between the amino acids and create a greater...
1) Choose one molecule from the set and create an 8-step synthesis scheme using the chosen molecule as your starting material. You need to write the complete set of reagents and draw the product expected from each step. Reagents typically used together are considered one step, eg. 1) LAH 2) H.O should be considered as one step Your 8 steps must include at least one reaction from each of the chapters, aldehydes and ketones, carboxylic acid derivatives, alcohols. You can...
What are the three functional groups that comprise a nucleotide? What do nucleotides have in common with amino acids or simple sugars? When the structure of DNA was first elucidated, many biologists quickly saw how this structure explained the passage of information from one generation to another. How does the structure of DNA explain generation-to-generation flow of information? In other words, give a brief description of the structure of DNA and tell how this structure allows for replication. Which of...
