- 1What are Mitosis' three purposesGrowth, repair, Asexual reproduction
- 2Neumonic!IPMAT
- 3What happens in Interphase?G1 (growth phase 1), S (synthesis), G2 (growth phase 2). Mitochondria grow and divide, normal metabolic processes, chromosome replicates forming 2 sister chromatids.
- 4Prophase???Chromosomes shorted and thicken, visible. The centrioles move to opposite poles (via cytoskeleton) and the nuclear membrane breaks down. nucleolus breaks down
- 5Metaphase???Chromosomes line up along the equator. Spindle fibres form and attach to the chromatids.
- 6Anaphase?The spindle fibres shorten, pulling the chromatids apart. Now chromosomes.
- 7TelophaseNuclear envelope and nucleolus reform. cytokinesis. chromatids uncoil into chromatic.
- 8Cytokinesis?The division of the cytoplasm and cell into two by constriction from the edges of the cell. Two genetically identical daughter cells formed.
- 9G1Cell prepares for DNA replication, organelles replicate, cell increases in size.
- 10SDNA replication occurs in the nucleus
- 11G2Cell continuous to increase in size, energy stores increase. Duplicated DNA checked for errors
- 12G0Differentiation- cell becomes specialised, carry out function until death, doesn't enter cell cycle again. DNA may be damaged- no longer divide enter permanent cell arrest. Age- old= less cells able to grow and repair by division
