Question

Q54) Consider the following statements on genome editing-

1. CRISPR-Cas9 is one of the techniques of genome editing.

2. CRISPR is an enzyme used to edit the DNA

3. Cas9 is used to determine the DNA segment to be altered.

Which of the above statements is/are true?

• A. a) 1 only
• B. b) 1 and 2 only
• C. c)1 and 3 only
• D. d) All of the above

Answer 1

The correct option is A

a) 1 only

Answer 54: A

Explanation: CRISPR (clustered regularly interspaced short palindromic repeats) is a collection of DNA sequences that lets scientists
to selectively edit genome parts and replace them with new DNA stretches. Cas9 is an enzyme that can edit DNA allowing the
alteration of genetic patterns through genome modification. CRISPR directs Cas9 where to cut and paste.
