Anaphase

• what happens during anaphase?

  • its a very rapid stage
  • the spindle fibres shorten and the centromeres separate, pulling the now separated chromatids to the poles, centromere first
• why do the spindle fibres shorten during anaphase?

  the microtubules that mark up the spindle fibres are polymers made of the protein tubulin - spindle fibres shorten because some of the tubulin is removed, from the centriole end
• what is this a diagram of?
