The microtubules that grow out from the centrosomes

Question

Quizplus · Accepted Answer

The microtubules that grow out from the centrosomes eventually attach to the centromeres of the chromosomes during mitosis, helping to pull the chromosomes apart equally into the two daughter cells. Choices A and B are incorrect because centrosomes and microtubules are involved in spindle formation and chromosome movement, not nuclear envelope breakdown or fusion. Choice C is incorrect because kinetochores are protein structures that form on the centromeres and serve as attachment sites for microtubules during mitosis, but they do not directly arise from the microtubules that grow out from the centrosomes.
