Question

Codon degeneracy means that

• A. Several of the amino acids are coded by more than one codon.
• B. One codon can code for many amino acids.
• C. One amino acid can be coded by only one codon.
• D. The codons are triplet nucleotide sequences.

Answer 1

The correct option is A Several of the amino acids are coded by more than one codon.

• Codon degeneracy means that the genetic code is degenerate. It means that there is more than one codon that specifies the single amino acid.
• The phenomenon in which several of the amino acids, each coded by more than one codon is called codon degeneracy.
  

Thus, the correct answer is option A.
