New cards
Prophase
chromatin condenses into chromosomes, nuclear membrane dissolves, centrosomes and microtubules migrate towards poles of the cell
2
New cards
Metaphase
microtubule spindle fibres attach to centromere of each pair of sister chromatids
Middle: Microtubule spindle fibres contraction cause sister chromatids to line up along center
Middle: Microtubule spindle fibres contraction cause sister chromatids to line up along center
3
New cards
Anaphase
Continued microtubule contraction separates sister chromatids (now chromosomes) and moves them to opposite poles
4
New cards
Telophase
microtubule spindle fibres and centrosomes separate, chromosomes arrive at poles, 2 new nuclear membranes form around each set of chromosomes, chromosomes decondense into chromatin
5
New cards
Cytokinesis
Contractile ring pulls cell membrane inwards, causing cleavage furrow which is pinched to form two identical daughter cells
