process of mitosis Flashcards
1
chromosomes supercoil. chromosome and the copy are called chromatids. the chromatids are joined at a centromere
2
centromere move to the opposite end of the cell. microtubules develop from each centriole from spanning of cell in each pole (spindle fibres). membrane of nucleus breaks down
3
chromosome line at the equator of cell, attaching to certain fibres at the centromeres.
4
chromosomes split from the centromere to different poles by microtubules
5
spindle fibres break down and new nucleus forms around the chromatids (cytokinesis). cells are replicas of parent cells
6
chromatids uncoil and cell grows to usual size, duplication of organelles occur here, nucleus replicates so each chromosome contains two chromatids.
