Question

What is degeneracy of genetic code?

Answer 1

Degeneracy of codons is the redundancy of the genetic code, exhibited as the multiplicity of three-base pair codon combinations that specify an amino acid. The degeneracy of the genetic code is what accounts for the existence of synonymous mutations.

Answer 2

When one amino acid is coded by many codes, it is called as the degeneracy of genetic code.

Explanation:

• The arrangement of nucleotides on DNA which decides the succession of amino acids in a polypeptide chain is named as Genetic code.

• Degeneracy is considered as one of the "salient features of genetic code" which means that one amino acid is coded by many triplet codons.  

• For example, Amino acid glycine is coded by GGU, GGA, GGC, and GGG whereas Valine is coded by GUU,  GUA, GUC and GUG.
