Degeneration of a genetic code is attributed to the:

Options

  1. Afirst member of a codon
  2. Bsecond member of codon
  3. Centire codon
  4. Dthird member of a codon

Correct answer

D. third member of a codon

Step-by-step 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.
