Understanding the Answer
Let's break down why this is correct
Answer
CRISPR‑Cas9 lets scientists cut DNA at a chosen spot so they can add, delete, or change genes. The Cas9 protein acts like a pair of scissors guided by a short RNA sequence that matches the target DNA. By directing the cut to a specific location, researchers can remove a harmful mutation, insert a new gene, or study how a gene works. This precise, easy‑to‑use method has become the main tool for editing genomes in research, medicine, and agriculture. For example, a faulty gene in a lab mouse can be replaced with a healthy version, fixing a disease‑causing defect.
Detailed Explanation
CRISPR-Cas9 lets scientists cut and paste DNA at a chosen spot. Other options are incorrect because People think CRISPR is just another way to breed crops; Some think CRISPR is mainly for vaccines.
