Mitosis

• What is the cell life?

  steps that take place as a cell grows then divides
• What happens to a cell when it isnt dividing?

  The DNA spreads out into long string
• What happens to a cell when it prepares for division?

  DNA condenses into chromosomes (Coiled packets of DNA)
• DNA contains a large amount of genes/characteristics. Give me an example of one.

  Eye colour
• How many pair of chromosomes do humans have?

  23
• A Eukaryotic cell has 2 copies of each chromosome, what are the 2 chromosomes called?

  A pair
• What do the cell fibres do?

  pull the arms of each chromosomes to the opposite side of the cell
• What is the opposite side of the cell called?

  Poles
• What happens in cell division?

  Cell membrane pull apart

  Forms 2 Daughter Cells

  Each cell has same DNA (Identical)
• What do the daughter cell contribute?

  Growth

  Development

  Repair

  Go through cycle again
• What is mitosis?

  When DNA divides
• Give me 3 reasons why new cells are required?

  Growth: We need more cells as we grow

  Development: Need new cell types as we develop tissue

  Repair: Need to replace the cells we loose each day
• When a cell divides by mitosis, how many cells are produced?
