A researcher might use site-directed mutagenesis because
A) spontaneous mutations occur too frequently to study.
B) using a mutagen yields results that are specific to a gene and not applicable everywhere in the genome.
C) mutation can happen at a specific site in the genome, compared to a mutagen that might cause mutations in several genes.
D) it works in humans but not in experimental organisms or cell culture.
E) it can treat genetic disease.

Question

Quizplus · Accepted Answer

Site-directed mutagenesis allows for the precise alteration of a specific site in a genome, compared to a mutagen that may cause mutations in multiple genes. This specificity is important for studying the effects of mutations on a particular gene or protein.
