The amino acid is threonine.
Each amino acid 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.
There are 64 combinations, 3 of these do not code for any amino acids and are thus known as non - sense codons. The remaining 61 combinations code for specific amino acids and are thus known as sense codons.
Thus ACC is one of the sense codons as it codes for the amino acid threonine.
