CH 11 Mitosis: Cell Reproduction
cell cycle-✔✔individual life cycle of the cell. has 7 phases.
Interphase-✔✔cell spends most of its life in this phase
G1 phase-✔✔cell increases in size and produces molecules needed for DNA
replication
G0 phase-✔✔resting state for the cell during life cycle. cell doesn't divide once it
reaches maturity
S phase-✔✔cell copies chromosome for DNA replication
G2 phase-✔✔produces proteins needed for division. end of interphase
mitosis-✔✔nucleus divides
cytoplasmic division-✔✔cytoplasm divides. now have 2 daughter cells
diploid-✔✔one set of chromosomes from each parent
homologous chromsomes-✔✔identical chromosomes. made during mitosis. only found
in females.
checkpoint genes-✔✔look for mistakes, damage, triggers etc. to stop or proceed with
cell life cycle
apoptosis-✔✔self destruct button for cell death. triggered by major mistakes that
checkpoint genes can't fix.
asexual reproduction-✔✔single parent makes identical offspring
stages of mitosis-✔✔prophase, metaphase, anaphase, telophase
prophase-✔✔chromosomes duplicate and thicken. centrosomes move to opposite
sides of the cell
