What happens in the prophase in mitosis?
Chromosomes become visible, the nucleus disappears, the mitotic spindle forms and the nuclear envelope disappears.
What happens in metaphase 2 during meiosis ?
The chromosomes become arranged on the metaphase plate.

It means when the chromosomes separate and start to move towards the opposite poles of the cell, as a result of the action of the spindle.
