Question

Quizplus · Accepted Answer

A small (one base pair) insertion in the middle of the coding region of a gene will create a frameshift mutation, which alters the reading frame of the gene sequence and can cause a significant change in the resulting amino acid sequence. This is because the genetic code is read in triplets (codons) and the insertion shifts the reading frame by one base pair, causing all subsequent codons to be different. This can lead to a non-functional protein or a protein with altered function. The other choices (A, B, C, D) do not accurately describe the effects of a small insertion in the coding region of a gene.
