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.
