Question

Gow many nucleotides are needed to code for a specific amino acid

Answer 1

Every three nucleotides = 1 amino acid, so 300/3 = 100, but the stop codon does not code for an amino acid, therefore 99 amino acids. 5. If a protein has 150 amino acids, how many DNA nucleotides would make up the coding region of the gene? 150 x 3 = 450, plus one codon for stop, 450 + 3 = 453.
