Describe the appearance and behaviour of chromosomes during mitosis (5)
During prophase, chromosomes supercoil and condense to become visible
Chromosomes appear as 2 identical sister chromatids joined by a centromere
During metaphase chromosomes line up on the equator of the left of the cell
Chromosomes attach to spindle fibres by their centromeres
During anaphase the centromere splits
Sister chromatids are pulled to the opposite poles of the cell making it V-shaped
During telophase, chromatids uncoil and become thinner
