What Does Disappearance of the Nuclear Envelope Permit in Human

Question

What does disappearance of the nuclear envelope permit in human and many other eukaryotic cells?
A)cytokinesis
B)the attachment of microtubules to kinetochores
C)the splitting of the centrosomes
D)the disassembly of the nucleolus
E)replication of DNA

Accepted Answer

The disappearance of the nuclear envelope during mitosis allows for microtubules to attach to kinetochores, which are protein structures on the chromosomes. This attachment is necessary for the proper alignment and separation of the chromosomes during cell division.
