Question

Which of the following statements is correct regarding the number of codons and their degeneracy?

• A. There are 20 codons, and all of them exhibit degeneracy.
• B. There are 64 codons, and none of them exhibit degeneracy.
• C. There are 64 codons, and some of them exhibit degeneracy.
• D. There are 20 codons, and none of them exhibit degeneracy.

Hint:

Degeneracy of the genetic code ensures redundancy and minimizes the effects of mutations. Although there are 64 codons, only 20 amino acids are encoded, leading to multiple codons for certain amino acids.
