Question

What 3 activities occur during prophase? Do they occur simultaneously?

Answer 1

During prophase of mitosis, three main activities occur: condensation of chromatin, formation of sister chromatids, and disintegration of nuclear envelope.

Step-by-step explanation:

During prophase of mitosis, three main activities occur:

1. Condensation of Chromatin: The loosely packed chromatin coils and condenses into visible chromosomes.
2. Formation of Sister Chromatids: Each chromosome becomes visible with its identical partner attached, forming sister chromatids.
3. Disintegration of Nuclear Envelope: The nucleolus disappears, and the nuclear envelope breaks down.

These activities do not occur simultaneously, but they happen in a sequential order.
