Explanation:
Detailed explanation-1: -In the second step of protein synthesis-translation-tRNA and mRNA interact to code amino acids into growing polypeptide chains.
Detailed explanation-2: -2) Peptide bond formation: a peptide bond is formed between the incoming amino acid (carried by a tRNA in the A site) and methionine (a tRNA charged with methionine attached to the P site during initiation).
Detailed explanation-3: -Step 2: Elongation Elongation is the addition of nucleotides to the mRNA strand. RNA polymerase reads the unwound DNA strand and builds the mRNA molecule, using complementary base pairs. During this process, an adenine (A) in the DNA binds to an uracil (U) in the RNA.
