<u>Answer</u>:
It is important for the chromosomes to condense during mitosis to facilitate chromosome movement.
<u>Explanation</u>:
The chemical called colchicine is found to be used during the process of mitosis, so as to freeze the cells, which can stop or prevent the movement of the chromosomes. This process is also essential for the faithful genome replication or transmission to those daughter cells. During the interphase cell division occurs but during the prophase the cell condensation is found to be happening. Before the process of the mitosis chromosomes are allowed to move and during this entangled and breaking were also noticed.
