- Cell Division
- Prokaryotic Cells
- The Process is called BINARY FISSION
- 1) Circular DNA molecule replicates
- 2) The plasmids replicate
- 3) Cell membrane grows between DNA dividing the cytoplasm in 2
- New Cell wall forms dividing original cell into 2 daughter cells
- Eukaryotic Cells
- This Process is Mitosis
- Prophase- the chromsomes becomes visible and the nucleolus and nuclear envelope disintergrates
- Metaphase- spindles form and the chromosomes line up at the equator of the cell
- Anaphase- the spindle fibres attach to chromatids and contract pulling them towards opposite poles
- Telephase- Chromosomes reach poles and become distinct, spindle fibres disintegrate and the nucleolus and nuclear envelope reappear
- Importance of Mitosis is that it makes exact copies so is essential because of growth repair and reproduction
- Cancer result in damage to genes causing uncontrollable growth of division of cells
- Prokaryotic Cells
