The nuclear membrane must break down because the chromosomes will have to be separated into two different regions. The nuclear membrane would be in the way.
Picture a sandwich bag full of coins. There are four of every coin. Can we divide the coins equally and give the two resulting groups of coins to two people without taking them out of the bag?

the nuclear membrane of the nucleus contains the genetic material, the chromosomes. the presence of the nuclear membrane will hinder the chromosomes from going to the daughter cells.
the CHROMATIN FIBERS which contain the DNA must be tightly coiled for easier 'movement' of the chromosomes to the opposite poles. it would be very tedious for the uncoiled chromatin fibers to move to the opposite poles.
