The polypeptide consists of 20 amino acids. Determine the number of nucleotides in the region of the gene that encodes the primary structure of this polypeptide, the number of codons per m-RNA corresponding to these amino acids, and the number of t-RNA molecules involved in the biosynthesis of this polypeptide (it should be noted that one t-RNA delivers one to the ribosome amino acid). Explain the answer.
1.The genetic code is triplet; therefore, the region of the DNA gene encoding a polypeptide of 20 amino acids contains
20 x 3 = 60 nucleotides
2.informational part of i-RNA contains 20 codons
3. for the biosynthesis of this polypeptide, 20 t-RNA molecules are required.
