Answer :


(b) (i) One codon codes for one amino acid. Each codon has 3 base pairs. Since the polypeptide consists of 14 different amino acids, this indicates that there are 14 codons. Therefore, the total number of base pairs = 14 × 3 = 42 base pairs.

ii) One tRNA is required for charging one amino acid. Since there are 14 different amino acids, 14 different types of tRNA are needed for the synthesis of the given polypeptide.
