If a polypeptide chain is 30 amino acids, how many nucleotides will make up the coding mRNA strand? 93
30
33
90
96

3 nucleotide require to produce one amino acid.As 30 amino acid , it requires 90 nucleotides including start codon but a polypeptide chain have a stop codon at last therefore 93 nucleotide will make up the coding mRNA strand.

The stop codon may be UAA ,UAG ,UGA they encode no amino acid.

answer; i believe that the correct answer is (b) melosis; plz check first.good luck

answer; i believe the answer is (polygenic inheritance;
