Question 3

CRISPR-Cas9 technology has revolutionized gene editing. Which of the following statements accurately describes its core principle and application in addressing genetic disorders?

Accepted Answer

B. It utilizes a guide RNA to direct a nuclease enzyme to specific DNA sequences, allowing precise cuts for gene inactivation or correction. — The correct answer is B. CRISPR-Cas9 technology uses a guide RNA (gRNA) to precisely target a specific DNA sequence, where the Cas9 nuclease enzyme then makes a cut. This allows for gene inactivation, correction of mutations, or insertion of new genetic material at a precise location. Option A describes traditional gene therapy methods using viral vectors to deliver entire genes. Option C refers to post-transcriptional or post-translational modifications, not direct gene editing. Option D describes random mutagenesis, which is not the controlled and precise mechanism of CRISPR.

Answer

A. It involves inserting entire functional genes into target cells using viral vectors, replacing defective ones.

Answer

C. It primarily focuses on altering the protein products of genes post-transcription, without directly modifying the DNA sequence.

Answer

D. It induces random mutations across the genome to increase genetic diversity, hoping for a beneficial outcome.
