3.24c - Mitosis

interphase

- this is where DNA replication occurs

prophase

-Membrane breaks down

- chromosomes become visible, visible as a pair of chromatidss

late prophase

-inside the cell the network of protein molecules known as the spindle/ fibres 

-chromosome pairs will move towards the spindle and will eventually join to one of the spindle

metaphase

-pair of chromatids --> attach to spindle fibre = centromere

- arranged across the middle, which is arranged across the equator ot the cell

anaphase

- the spindle fibres shorten puling the spindle fibres apart

- the pair of chromatics are moving apart

- moving to the poles of the cell

- separation of pair of chromatics

telophase

- nucleus begin to reform around the chromosomes at either end of the cell

- formation of two nuclei at opposite ends of the cells

cytokinesis

- cell split into two (not part of mitosis)

- in the middle part of the cell it begins to move inwards dividing the cytoplasm in half- membrane fusing across the equator forming two cells ( each contain a chromosome)
