Slide 3
MITOSIS It is a process in which a eukaryotic cell splits into
2, which is formed into 2 daughter cells It includes: Interphase,
Prophase, Metaphase, Anaphase, and Telophase/ Cytokinesis
Slide 4
Mitosis
Slide 5
Meiosis A process that divides parent cells to make half
genetic formula from each parent Includes: Meiosis 1- Prophase 1,
metaphase 1, Anaphase 1, and Telophase 1/ Cytokinesis Meiosis 2-
Prophase 2, Metaphase 2, Anaphase 2, and Telophase 2
Slide 6
Slide 7
Cell Cycle Control Contains 3 Checkpoints ( points where stop/
go signals regulate the cell cycle) Checkpoints are: G1- Most
important!!!, G2, and M-spindle (metaphase)
Slide 8
Slide 9
Internal Regulatory Molecules A group of proteins that control
the progression of cells in the cell cycle by activating CDK
(Cyclin- Dependent Kinase) Cyclin levels fluctuate into the cells
Specific cyclin: CDK complex that allows cells to pass G2 and go to
and go to the M phase
Slide 10
External Regulatory Factors Growth factor: proteins released by
other cells to stimulate cell division Density-dependent
inhibition: crowded cells normally stop dividing; cell- surface
protein binds to adjoining to inhibit growth Anchorage dependence:
cells must be attached to another cell or extracellular matrix to
divide
