AVprozaik [17]

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
