Check points
Points where events of the cell cycle are checked by proteins to check nothings wrong
G1 checkpoint
Determines if the cell is ready to proceed w/ division(enough nutrients)
G2 checkpoint
Makes sure the cell is large enough to divide,checks new dna
M checkpoint
Checks number of chromosomes
Cyclin dependent kinase(CDK)
Enzymes that become active when bonded w/cyclins
Helps initiate chemical reactions for the cell to move on the cycle
Cyclins
Specialized protein that regulate the checkpoint
Cancer
Disease that is created from uncontrolled division/growth of cells
Cause tumors
Stem cells
Cells that can develop into a variety of different cell types
Cell differentiation
When a cell becomes a specific type of cell

Totipotent
Best cell
Can become any type of cell
Pluripotent
2nd
Stem cells that can differentiate into any cell type with in the layer(endoderm, mesoderm, ectoderm)
Multipotent
3rd
