Question

multiple choice question
there are ____ possible codons and ____ different amino acids, therefore more than one codon can code for a particular amino acid.
27; 22
32; 30
64; 20

Explanation:

In the genetic code, since there are 4 nucleotides and codons are triplets (4×4×4 = 64 possible codons), and there are 20 different amino - acids. This leads to the phenomenon of degeneracy where more than one codon can code for a particular amino - acid.

Answer:

C. 64; 20
