Final answer:
During elophase in cell division, several events occur including chromosomes spreading out into chromatin, the nuclear envelope reforming around chromosomes, and the spindle fibers breaking down. The statement that does NOT occur during elophase is that the nucleolus disappears.
Step-by-step explanation:
During elophase, the following events occur:
- Chromosomes spread out into chromatin: In elophase, the condensed chromosomes start to uncoil and become less compact, forming chromatin.
- Nuclear envelope reforms around chromosomes: In elophase, the nuclear envelope reforms around the separated chromosomes, enclosing them within the nucleus.
- Nucleolus disappears: The nucleolus, which is responsible for producing ribosomes, disappears during elophase.
- Spindle fibers break down: The spindle fibers, which aid in separating the chromosomes, start to break down during elophase.
- Centrioles dissolve and disappear: Centrioles, which play a role in organizing the spindle fibers, dissolve and disappear during elophase.
Therefore, the statement that does NOT occur during elophase is that the nucleolus disappears.
