QUESTION 14 Use the following image to answer questions 9 and 10. The numbered circles represent amino acids. Structures A, B, 5' 3' 3 The next step in the translation of this mRNA will be the formation of a peptide bond between which two amino aclds? amino acid 2 and amino acid 3 O amino acid 2 and amino acid 4 O amino acid 1 and amino acid 3 O amino acid 1 and amino acid 2 QUESTION 15 After the peptide bond forms, what will happen? tRNA A will be carrying the polypeptide and it will shift to the P site.

Explanation / Answer

The answer is: amino acid 2 and amino acid 3.

Amino acid 1 is the first amino acid of the protein chain that is methionine, as protein synthesis proceeds, amino acids are added to the growing polypeptide via formation of peptide bonds. In the given picture the next step is the formation of a peptide bond between amino acid 2 and amino acid 3, following which tRNA carrying amino acid 4 will enter A site.
