Document Summary
The life of a cell how cell is built, how it communicates, how it dies, how it grows. Mitosis interphase, prophase, prometaphase, metaphase, anaphase, telophase and cytokinesis. Some cells divide very often (roots of plants, epithelium of skin, intestines, etc. ); some don"t divide in adults (rbcs, muscles, most neurons) Cell cycle regulation the majority of the cell"s life is in interphase. Check for broken pieces, is everything wrapped properly in solenoid ii. At the very end of g2 before initiating mitosis (g2/m checkpoint) damage checkpoint; if cell can"t be repaired, it will go to death. 1: g2 phase getting ready to separate the cells; build extra lipids and protein to make more membrane, duplicate organelles (mitos go through binary fission, golgi split their stacks) iii. Every checkpoint has proteins that act as molecule switches (go or no go) that respond to external and internal signaling information.
