The genetic code is described as 'degenerate' because:
AThe code is unreliable
BThe code is different in every organism
CSome amino acids are coded by more than one codon
DCodons are read in groups of four bases
Answer & Solution
Correct answer: C. Some amino acids are coded by more than one codon
**Degeneracy**: 64 codons for only 20 amino acids → **most amino acids are encoded by multiple synonymous codons**. E.g., serine has 6 codons; arginine has 6 codons. Generally the 3rd base is the redundant 'wobble' position.
