Chemotherapy utilizes chemicals to interrupt various parts of the cell cycle, targeting rapidly growing cells. Taxol® is an example of a drug that prevents mitosis phase from occurring. How this Taxol useful as a cancer treatment and how might targeting rapidly growing cells explain common chemotherapy side effects such as hair loss and nausea?
A. Taxol will stop the tumor from growing, but unfortunately it also impacts other fast-growing cells (like hair follicles and stomach lining cells), so normal cells get damaged as well.
B. Taxol will stop the tumor from continuing to divide, but unfortunately it also impacts other readily dividing cells (like hair follicles and stomach lining cells), so normal cells get damaged as well.
C. Taxol will stop the tumor from copying DNA, but unfortunately it also impacts DNA replication in other cells (like hair follicles and stomach lining cells), so normal cells don't get to continue through…
