B3- Cell cycle

• STAGE 1 OF CELL CYLE

  • Cell grows bigger
  • DNA replicates
  • increase in sub-cellular structures
• STAGE 2

  • a complete set if chromosomes are pulled to each end of the cell
  • nucleus divides to form two nuclei
• Stage 3


  cytoplasm and cell membrane divide to form two identical daughter cells
• THERAPEUTIC CLONING

  • cells from a patient's own body are used to create a cloned early embryo of themselves
  • stem cells from this embryo can be used for medical treatments and growing new organs
  • these stem cells have the same genes as the patient, so are less likely to be rejected when transplanted.
