Q. 1.With reference to CRISPR-Cas9, a gene editing method consider the following statements:
1.It edits genes by cutting the desired DNA and allowing natural DNA repair processes to take over.
2.This technology works at extremely high temperatures…
Which of the statements given above is/are correct?

[A] 1 only

[B] 2 only

[C] Both 1 and 2

[D] Neither 1 nor 2

Answer: A
Notes:

Statement 1: CRISPR-Cas9 edits genes by cutting the desired DNA and allowing natural DNA repair processes to take over.

Statement 2: The statement is incorrect. CRISPR-Cas9 technology can work at very low temperatures of 4 degree C but it works at moderate high temperatures only around 37 degrees C.
