Taxol works by interfering with the normal function of microtubules during cell division. Microtubules are essential components of the cell's cytoskeleton and are crucial for the process of mitosis. By stabilizing the microtubules and preventing their disassembly, Taxol effectively halts the division of cancer cells, leading to cell death. This mechanism makes Taxol a powerful agent against rapidly dividing cells, a hallmark of cancer.
