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 act as an antioxidant in a person's cells, removing toxins that might otherwise damage DNA. 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 be a substitute for chemotherapy

Answer:

B

Explanation:

CRISPR-Cas9 is a gene-editing mechanism that is harnessed from bacteria’s immune system used to cut apart foreign genetic material such as that of bacteriophages. CRISPR-Ca9 has a guide sequence that is used to identify the target sequence. The Cas9 enzyme cuts this target DNA and is replaced with the required piece.

In cancer treatment, the mutated DNA can be replaced, this way, with the wild type.
