Can You Synthesize What You've Learned? ere given to cancer patients in an amempt to hait or slow the growth of a tumor, which is composed of rapidly dviding cels tain chemotherapy drugs exert their actions by interfering with mitosis. For example, some drugs act to prevent microtubules from lengthening or are protein fiements that attach to chromosomes and centrioles, forming the mitotic spinde, which moves the chromosomes during mitosis. Based on this role ot microtubules during mitosis, with which stagels) of mtosis would these drugs most iRely interfere 30. What is the function of rough endoplasmic reticulum?

Explanation / Answer

29. Microtubules are polymers which are of tubular shape, which would be involved in mitosis. The mitotic spindle or the spindle apparatus is the cytoskeletal structure that would be formed at the time of cell division. This is formed for separation of the sister chromatids within the daughter cells. Microtubules are referred to as the structures that would be pulling the chromosomes away from one another. Microtubules would be formed in the prophase phase of mitosis, which attach to one another to the kinetochores in the metaphase. Hence, the mitotic inhibitors would be affecting metaphase, since these disrupt the already formed mucrotubules.
