1. DEFINITION
1.1. stages that cells pass through to allow them to divide and produce new cells. (copiying genetics meterials)
2. HOW DOES IT WORK
2.1. understand how all the DNA is arranged in a cell
2.2. each daugther cell needs a complete copy of all the genetics information or genome
2.3. PROCESS
2.3.1. DNA replication
2.3.2. sister chromatid seprate before the cells devide
2.3.3. daugther cells each get a copy
3. CELLS
3.1. prokaryotes
3.1.1. have just one circular DNA molecules
3.2. eukaryotes
3.2.1. have many differents linear DNA molecules, called chromosomes
4. WHAT HAPPEN IF REGULATION GONE WRONG
4.1. CANCER
4.1.1. involves cells that deviding out of control (tumor)
5. CHROMOSOMES
5.1. consist of a DNA molecules wrapped around protein called histones to form nucleosomes
5.2. chromatin undergoes supercoiling
5.3. coiling up for storage and uncoil to replicate
5.3.1. during replication every chromosomes is duplicated to form sister chromatid
6. STAGES OF THE CELL CYCLE
6.1. M phase
6.1.1. mitotic phase
6.1.2. cell dividing
6.2. ineterpahse
6.2.1. G1 phase
6.2.1.1. first gap
6.2.2. S phase
6.2.2.1. synthesis
6.2.3. G2 phase
6.2.3.1. second gap
7. MOLECULES PROTIEN
7.1. protein kinase
7.1.1. are enzymes that activated od deactivated others protein by phosphorylation
7.2. cyclin
7.2.1. family of proteins that controls the progression of a cell through the cell cycle by activating cyclin-dependent kinase enzymes or group of enzymes required for synthesis of cell cycle.
