Question

A gene editing technology called CRISPR-Cas9 uses cellular machinery to change the cell's genetic material. How might this technology be useful in treating diseases like cancer?

A. CRISPR-Cas9 could be a substitute for chemotherapy.

B. CRISPR-Cas9 could remove from patients the genetic mutations that cause a specific cancer before the cancer begins.

C. CRISPR-Cas9 could remove any DNA damage caused by smoking.

D. CRISPR-Cas9 could act as an antioxidant in a person's cells, removing toxins that might otherwise damage DNA.

Answer 1

(c) CRISPR-Cas9 have the ability to strike a specific sequence in the whole genome. So with the help of it we can Target the part of DNA that is mutated (damaged) and hence can stop cancer.
