Answer:
9 amino acids
Explanation:
A segment of a gene that has 27 nucleotides will code for<u> 9 amino acids.</u>
<em>Each codon on the gene potentially represents an amino acid and a codon is made up of 3 nucleotides each. Hence, in order to find out the total number of amino acids that a gene segment with 27 nucleotides can code for, the number of nucleotides should be divided by 3.</em>
number of amino acids = number of nucleotides/3
27/3 = 9 codons/amino acids
