Q

What does anaphase require and where does it get it from? - 2 points

A

energy, from mitochondria

17
Q

Where does the spindle pull the chromatids to during anaphase?

A

Opposite poles of the cell

18
Q

What happens during anaphase? - 2 points

A
  • chromatids separate at their centromeres
  • chromatids are pulled towards opposite poles of the cell by the spindle
19
Q

What happens during the last stage of mitosis (telophase)? -

A
