Take Test: E 3 matohe Remaining Time: 54 minutes, 12 seconds s Question Completion Status: QUESTIONS Due to a mutation in gene A, amino acid 'Glu' In position 15 of enzyme A (the wild polypeptide) is replaced by 'Ala'. Individuals who are heterozygous for the mutant allele (Aa) don't have any phenotypic alterations. Based on this observation, which of the following is correct about this mutation? OA The mutation has occurred in the promoter OB The mutation has occurred in the last intron of the gene OC. The mutation is a base insertion in the second exon. OD.The mutation is recessive. OE. The mutation is a neutral dominant mutation. OF Two of the above are correct QUESTION 6 Initiation of translation: Click Save and Submit to sove and submit. Click Sove A Answers to save all answers.

Explanation / Answer

The mutation is recessive.

The loss of amino acid in one allele in heterozygous individuals is not enough for phenotypic change. It means the wild type allele alone has enough expression of protein to maintain the normal phenotype. This suggests that the mutation is recessive.
