Document Summary
= cells need to get rid of bad things - in this case, getting rid of the entire cell via programmed cell death. Note: necrosis is getting rid of external damage (not normal), this is programmed cell death (different & normal) Many dangerous things inside a cell that can be dangerous if released/just floating around. Specific pathway to get rid of cells we don"t want. Active cellular process that is morphologically distinct from necrosis (where cell swell and burst) In apoptosis, things are fragmented into little bits call apoptotic bodies" which are then removed via phagocytic cells (like macrophages) Getting rid of dna is particularly important because it can be very. Nucleus has to be fragmented in a very specific way. Dna is cut and packaged to be taken away very neatly. Fragments are cut that are very manageable - you can run apoptotic. Dna on a gel without the need to cut it yourself: elegans:
