Question

Quizplus · Accepted Answer

Targeted mutations involve manipulating specific genes to impair or enhance the production of a particular protein. This is usually done using techniques like CRISPR/Cas9 gene editing to precisely target and modify specific genes. Injecting chemicals to block the production of transmitters (A) or inducing random genetic mutations (D) are not specific mutations and can have unpredictable effects. Inserting genes to overproduce a functional protein (B) could also be a targeted mutation, but the question specifically asks about impairing the production of a protein. Random mutation of a gene allele (E) is also not targeted and can have unpredictable effects.
