Question & Answer
Choose the Best Answer
By using a guide RNA to direct Cas9 to specific DNA sequences
By randomly cutting DNA at various sites throughout the genome
By replacing entire genes with new sequences
By synthesizing a new genome from scratch
Understanding the Answer
Let's break down why this is correct
The system uses a guide RNA, a short RNA strand that matches a specific DNA sequence, to direct the Cas9 protein to that spot. Other options are incorrect because Some think the system cuts DNA randomly, but it actually follows the guide RNA; CRISPR does not replace whole genes; it edits small sections.

Definition
CRISPR-Cas9 Genome Editing is a revolutionary method used in genetic engineering that enables precise modifications of DNA sequences in living organisms. This technology utilizes the Cas9 protein, which acts as molecular scissors to cut DNA at specific sites, guided by a sequence known as Protospacer or guide RNA. The significance of this method in business lies in its potential applications across various fields, including medicine, agriculture, and biotechnology, allowing companies to innovate and develop solutions for complex challenges.
