1. Process of Cell Division

Process of Cell Division

2. Chromosomes Made of DNA and proteins
Prokaryotes – single circle of DNA
Eukaryotes – DNA is wrapped around histone proteins to protect it and make it fit in nucleus = chromatin
Chromatin condenses into chromosome shape before cell division

4. When chromosomes copy, each new copy is a chromatid (or sister chromatid)
Sister chromatids are held together at the centromere by a kinetochore protein

5. Cell Cycle Prokaryotes Cell grows Copies DNA
Membrane pinches in between 2 copies of DNA
2 new genetically identical cells formed
= binary fission

7. Eukaryotes
more complex
4 (5) phases; length of phase depends on type of cell

8. G1 phase –
S phase –
G2 phase –
M phase –
* Mitosis –
* Cytokinesis -

9. G0 phase – when cell exits cycle and lives its life
