Cell Replication
(Non-Reductive)
- Eukaryotes (Mitosis)
- 1. Interphase
- G1
- S
- G2
- 2. Prophase (chromosomes condense and nuclear envelope
breaks down)
- 3. Metaphase (chromosomes line up at equator and
spindle fibres form)
- 4. Anaphase
- Early (spindle fibres contract to start pulling
chromosomes to ends)
- Late (chromosomes at opposite ends.
Cleavage furrow appears)
- 5. Telohase (Nuclear membrane reforms and cytokinesis occurs)
- Cytokinesis
- Plants
- Cell plate forms (new cell wall)
- Animals
- Plasma membrane from one side joins the other
- Prokaryotes (Binary fission)
- 1. Cell Doubles in Size
- 2. DNA Replicates
- 3. New membrane forms and cells split
- Stem Cells
- Embryonic (can differential into any type of cell)
- Adult (make cells for particular tissue)
- Cell Cycle (heavily controlled)
- Replication error spotted leads to cell apoptosis
- Replication error NOT spotted can lead to uncontrolled cell growth
