The person who marked it has actually already explained it. Three nucleotides in the DNA code for each amino acid in the peptide. Have a read of this article in the fount of all human knowledge

Well
3 bases on nucleotide = 1 codon.
1 codon = 1 Amino acid,

So if you have 20 amino acids, then 20*3 (as 3 bases make one codon) = 60
