Question

What happens during prophase​

Answer 1

Chromosomes become visible, the nucleolus disappears, the mitotic spindle forms, and the nuclear envelope disappears. Chromosomes become more coiled and can be viewed under a light microscope. ... The nuclear envelope disappears at the end of prophase.

Step-by-step explanation:

Answer 2

Prophase is the first phase of M-phase of cell division which is marked by many changes taking place in the dividing cell which are:

1. Chromatin condenses and becomes more coiled.

2. Chromosomes are seen as a pair of sister chromatids with a centromere.

3. Nucleolus-site of rRNA synthesis disappears.

4. Mitotic spindle- formation begins between two pairs of centrioles.

5. Nuclear envelope- disappears at late prophase.
