]]> 2013-10-18 16:31:25 UTC https://padlet.com/vsbartnicki/valesb_mito-cyto/wish/14991913 Prophase (stage) vsbartnicki https://padlet.com/vsbartnicki/valesb_mito-cyto/wish/14992123 -chromatin condenses into tightly coiled chromosomes

-nuclear envelope breaks down; nucleous disappears

-centrosomes and centriols move to opposite side of the cell

-spindle fibers grow form the centrioles, radiating towards the center of the cell

-chromosomes align in the middle of the cell (pulled and moved by motor proteins)

-spindle fibers shorted-- pulling sister chromatids away towards center of the cell

-nuclear membrane starts to form

-chromosomes uncoil

-spindle fibers fall apart
