Prophase- *Nuclear membrane
disappears
( so chromosomes can
move around)
Metaphase- Chromosomes
line up in the middle of the cell
Anaphase-*Chromosome copies
pull apart from each other.
Telophase-<span>*Nuclear division
has finished and nuclear membrane reappears</span>
<span> This is the process for Meiosis 1 not for 2 (FYI)</span>
