Questions: In the Mitosis simulation, we studied the effects of the drug paclitaxel on cultured cells. Based on your examination in the simulation you were able to conclude: Paclitaxel had no effect on cell division Paclitaxel inhibits cell division Paclitaxel was not studied in the simulation Paclitaxel accelerates cell division

The answer is the second one: Paclitaxel inhibits cell division.

Explanation for each option:

1. Paclitaxel had no effect on cell division: This is incorrect. Paclitaxel is known to affect cell division by stabilizing microtubules, which prevents them from depolymerizing, thereby inhibiting the normal process of mitosis.

2. Paclitaxel inhibits cell division: This is correct. Paclitaxel is a chemotherapy drug that works by inhibiting cell division. It stabilizes the microtubule polymer and protects it from disassembly, which disrupts the normal mitotic process and prevents cells from dividing.

3. Paclitaxel was not studied in the simulation: This is incorrect. The question specifically mentions the study of paclitaxel in the simulation, so it was indeed part of the examination.

4. Paclitaxel accelerates cell division: This is incorrect. Paclitaxel does not accelerate cell division; rather, it inhibits it by interfering with the mitotic spindle function.

In summary, paclitaxel is known to inhibit cell division, which aligns with the correct answer.
