How do Cells Divide?
mitosis
Prophase
membrane dissassembles
DNA condenses into chromosomes
metaphase
spindle fibers attach to chromosomes
attach to centromere
work to align chromosomes along center of cell
M checkpoint
checks if chromosmes are alligned before being pulled apart
anaphase
Chromosomes are pulled apart
split into sister chromosomes
telophase
membrane forms around chromosome
DNA decondenses
interphase
G1
cell growth & development
G1 checkpoint
checks if cell is fully developed
if it isn't developed, to apoptosis
if fully developed, allowed to move onto S phase
Synthesis Phase
DNA duplication
G2
Organelle & protein duplication
G2 checkpoint
looks for DNA damage/ proper duplication
if DNA is damaged, apoptosis
if DNA isn't damaged, moves onto mitosis
Cancer
cell division
rapid cell divisioncreates abundance of cell
form into tumors
mutations
onco
promote cell growth
tumors begin to form
cell speeds through cell cycle
mutation
suppressor
monitor cell growth
prevents apoptosis
tumprs begin to form
DNA repair
fix mistakes in DNA pairings
mistakes left unfixed
