Mitosis

• Last phase of the cell cycle and occurs in somatic cells.
• produces 2 daughter cells
• Asexual reproduction is more common in the mitosis process
• KARYOKINESIS: division of the nucleus
• CYTOKINESIS: Cellular division
• PHASES IN MITOSIS:PPMAT

  Prophase

  Prometaphase

  Metaphase

  Anaphase

  Telophase
• facts; plant cells don’t have centrioles

  microtubules can also be called kinetical microtubules/ astromicrotubules
• Interphase only occurs during mitosis

  g1-5hrs

  s-7hrs

  g2-3hrs

  m-1hr(p-36mins,m-3mins,a-3mins,t-18mins
• PROPHASE-Nuclear condensation and loss of nucleolus
• PROMETAPHASE- Loss of nuclear envelope, chromosomes condense.
• METAPHASE-Alignment of chromosomes along the metaphase plate
• ANAPHASE-distinct separation of daughter chromosomes
• TELOPHASE(cytokinesis)- the nuclear envelope reforms and the cytoplasm/chromosome divides
• Mitosis-involved in the development, growth and replacement of cells (e.g. for tissue repair, etc.)
