Question

During what division can prophase be broken into substages?

Answer 1

Prophase can be broken into substages including nuclear envelope breakdown, chromatin condensation, centrosome migration, and spindle formation.

Step-by-step explanation:

In mitosis, prophase is the first phase and can be further divided into substages. The substages of prophase are:

1. Nuclear envelope breakdown: The nuclear envelope starts to break into small vesicles.
2. Chromatin condensation: The loosely packed chromatin coils and condenses into visible chromosomes.
3. Centrosome migration: The centrosomes begin to move to opposite poles of the cell.
4. Spindle formation: The microtubules that form the mitotic spindle extend between the centrosomes.

These substages occur sequentially during prophase.
