Talk about prophase.

First stage. Characterized by complex events, condensation of long chromatin fibers into chromosomes to make their seggregation possible. Which is triggered by phosphorylation of Histones and non-histones. Condensins are proteins that attach to chromosomes while condensing, scaffold shape. Cohesins join chromatids as well as centromere. Kinetochore proteins assemble to form button like structures bound on centromeres of each chromatid. These mediate the attachment to microtubules and motor proteins. Nucleoli disappear because no NOR.
