Question

what happens if a nuclear envelope exists in a cell ?

Answer 1

Chromosome segregation during cell division in higher eukaryotes is driven by a microtubule spindle formed in the cytoplasm. To allow the interaction of microtubules and chromosomes, the nuclear envelope breaks down in prophase, leading to an 'open' mitosis.

Answer 2

Answer:

idk if it hels u but here u go

Explanation:

A unique feature of the nucleus is that it disassembles and re-forms each time most cells divide. At the beginning of mitosis, the chromosomes condense, the nucleolus disappears, and the nuclear envelope breaks down, resulting in the release of most of the contents of the nucleus into the cytoplasm.
