Silent mutations occurs because codon is :: (A) Non overlapping, (B) Commaless, (C) Universal, (D) Degenerate
Answer is D. Degenerate Silent mutations occurs because codon is degenerate. Degeneracy/Redundancy is a propey of codons that each amino acid is having more than one codons. Silent mutations means a codon is replaced by another codon, which is coding for same amino acid.
