Document Summary
Bio130 lecture 24 later stages of mitosis. Green, yellow, and brown parts are all. Metaphase-anaphase transition plate: this is an important checkpoint. First, chromosomes condense depolymerization happens, the collar will move. The microtubules are treadmilling, even if they look stable. The pericentriolar material is a cloud of proteins: on it you have nucleated microtubules. The interdigitating ones are polar microtubules, along the middle. Each centrosome has a pair of centrioles. A special depolymerase removes heterodimer from the minus end. Anaphase does not start until all chromosomes are aligned on the metaphase. Sister chromatids separate to form the two daughter. When anaphase is triggered, a protease called. Added in t-form, but along the middle it is d form. Does not require atp: both ends are being depolymerized. In green, depolymerase that removes heterodimers at plus end. The collar moves right because the plus end is moving right. After arrangement to give good structure, the phospholipid bilayer fuses together.
