Question

Quizplus · Accepted Answer

The disassembly of the three major components of the nuclear envelope is initiated by phosphorylation of key substrates by mitotic kinases, particularly cyclin B-Cdk1. This leads to the dissociation of nuclear lamins from chromosomes and the disassembly of the nuclear envelope.
