Question

the entire genetic code consists of ____ amino acids and ____ codons. a 30, 75 b 30, 68 c 20, 20 d 20, 64

Explanation:

The genetic code has 20 standard amino acids. There are 4 nucleotide bases (A, U, C, G). Codons are triplets of nucleotides. The number of possible codons is \(4\times4\times4 = 64\) (since for each of the three positions in the codon, there are 4 choices of nucleotides).

Answer:

d. 20, 64
