Quizplus · Accepted Answer

In knockout experiments, genes are mutated or deleted to prevent their expression. This is usually done to understand the function of a specific gene by observing the changes that occur when that gene is not expressed. This can be achieved through various techniques, such as CRISPR-Cas9 or homologous recombination. Thus, the best choice is C.
