Question

On translation, mRNA produces a polypeptide chain, which contains 50 amino acids. If 26th codon of mRNA UUU mutated and changed to UUC, then the polypeptide chain will be (A) Completely changed (B) Partially changed (C) Not changed (D) Only one amino acid changed

Codon UUU and UUC both codes for amino acid phenylalanine, hence polypeptide chain will not change.

Completely changed

Partially changed

Not changed

Only one amino acid changed
