Taxol is an anticancer drug extracted from the Pacific yew tree. In animal cells, taxol disrupts microtubule formation by binding to microtubules and accelerating their assembly from the protein precursor, tubulin. Surprisingly, this stops mitosis. Specifically, taxol must affect A) the fibers of the mitotic spindle. Which of the following are primarily responsible for cytokinesis in plant cells? B) Golgi-derived vesicles During which phases of mitosis are chromosomes composed of two chromatids? E) from G 2 of interphase through metaphase In which group of eukaryotic organisms does the nuclear envelope remain intact during mitosis? B) dinoflagellates C) diatoms D) B and C only Movement of the chromosomes during anaphase would be most affected by a drug that D) prevents shortening of microtubules In order for anaphase to begin, which of the following must occur? C) Cohesin must be cleaved enzymatically. Why do chromosomes coil during mitosis B) to allow the chromosomes to move without becoming entangled and breaking Several organisms, primarily Protists, have what are called intermediate mitotic organization.These Protists are intermediate in what sense? D) They maintain a nuclear envelope during division
