Question

Out of 64 codons only 61 codes for the 20 different amino acids. This character of genetic code is called as

• A. Degeneracy
• B. Non ambiguous nature
• C. Redundancy
• D. Overlapping

Answer 1

The correct option is A Degeneracy

Out of 64 codons only 61 codes for the 20 different amino acids. This character of genetic code is called as degeneracy. Degeneracy of codons is the redundancy of the genetic code, exhibited as the multiplicity of three-codon combinations specifying an amino acid. The degeneracy of the genetic code is what accounts for the existence of synonymous mutations.
