The correct answer for this question would be A) Nnew = Nold.
<span>tRNA carries a single amino acid to the ribosome.
It fits the codon on the mRNA in the ribosome with it's anti-codon.
The ribosome has peptidyl-transferase activity which catalyses the peptide bond between 2 amino acids on 2 tRNAs in the ribosome.
One tRNA is released and then picks up another amino acid depending on its anti-codon.
