Each position of a codon can be occupied by one of four nucleotides. What is the minimum number of nucleotides per codon necessary to specify all 20 of the amino acids that are found in proteins

The minimum number of nucleotides per codon necessary to specify all 20 amino acids that are found in proteins is 3

Explanation:

There are four nucleic acids in the RNA, adenine uracil, guanine, cytosine. Each of them combines in groups of three to give the different amino acids. In total,  there are 64 different combinations of nucleic acids that codify the 20 amino acids that we need for our vital functions.

the answer is b. glad to .
