Which of the following mutations is most likely to cause a phenotypic change?

Question

Quizplus · Accepted Answer

A single nucleotide deletion in an exon coding for an active site of a protein is most likely to cause a phenotypic change because it is a frameshift mutation that alters the reading frame, resulting in a different sequence of amino acids. This can affect the structure and function of the protein, potentially causing a change in phenotype. The other mutations listed may not have as significant an impact on phenotype.
