Q165 / 200 · NEET 2003 · Zoology

Degeneration of a genetic code is attributed to the:

A
first member of a codon
B
second member of codon
C
entire codon
Correct answer
D
third member of a codon

Solution

Each codon is specific for only one amino acid (or one stop signal), yet the genetic code is described as degenerate, or redundant, because a single amino acid may be coded for by more than one codon. The codons that code for one amino acid can differ in any of their places; nevertheless, the second or third codon is more frequent.

Hence, the correct answer is option: 'D'.
