3.24c Mitosis

Interphase - DNA replication process inside Nucleus



interphase
- nucleus breaks down
- visible pair of chromatids

late prophase
- spindle fibers (protein molecules)
- range from one pole of cell to the other

metaphase
- chromatids attach to the fiber by the central near

anaphase
- fibre shorten pulling chromatids apart
- move to opposite poles of cell
- separation of chromatid pair

telophase
- nucleus reforms around chromosomes at either end of cell

cytokinesis
- cell splits into two
- each cell contain identical chromosomes
