Q

Describe the 4 things that happen in prophase

A
  • DNA supercoil and condenses
  • Nuclear envelope disintegrates
  • Centrioles divide and move to opposite poles
  • Spindle apparatus is formed from spindle fibres and centrioles

Q

Describe the 2 things that happen in metaphase

A
  • Spindle fibres attach onto centromeres of chromosomes
  • Chromosomes are pulled to the equator to the cell and line up
