It was at that POINT MUTATION began
In biology, the active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction. The active site consists of residues that form temporary bonds with the substrate (binding site) and residues that catalyse a reaction of that substrate (catalytic site).
Answer:
They destroy the DNA or RNA
Explanation:
Cancer drugs work by damaging the RNA or DNA. The faster the cancer cells divide, the more likely it is that chemotherapy will kill the cells, causing the tumor to shrink. They also induce apoptosis. Radiation therapy is a cancer treatment that uses high doses of radiation to kill cancer cells and shrink tumors. The radiations also induce apoptosis. Cancer cells whose DNA is damaged beyond repair stops dividing and die. The damaged cells die, they are broken down and removed by the body.
