Question

"What is a result of preventing spindle fibers from forming?"

The answer choices are:
A. The cell cycle skips G0 phase and repeats G1 phase.
B. The cell cycle skips S phase and proceeds to G2 phase.
C. Mitotic division is skipped, and the cell cycle proceeds to cytokinesis.
D. Mitotic division stops in metaphase and cannot proceed to anaphase.

Answer 1

Preventing the formation of spindle fibers would most likely halt mitotic division at metaphase, as spindle fibers are crucial for chromosome alignment and separation.

Step-by-step explanation:

If spindle fibers are prevented from forming, the most likely result is that mitotic division stops in metaphase and cannot proceed to anaphase. This happens because spindle fibers play a critical role in aligning chromosomes during metaphase and then in separating sister chromatids during anaphase. In their absence, chromosomes would not be able to properly align or separate, which is essential for cell division. Therefore, the correct answer to this question is D.
