Benjamin Vaughn · Answer 1

The best answer is A.

In most living organisms, codons are assigned to the same amino acids.

Each amino acid is coded for by a set of three nucleotides in DNA. Each set of nucleotides is called a codon or triplet. The set of all possible three-nucleotide combinations is called the genetic code or triplet code. It is universal.

These combinations are 64 in number. Of these, 3 do not code for any amino acid and are called non-sense codons, which leaves 61 which code for specific amino acids and are called sense codons.
