Which of the following describes prophase of mitosis?
tigry1 [53]

Answer:

Daughter chromosomes move toward opposite poles of the cell.

Explanation:

Prophase is the beginning of cell division. At this stage, the CHROMATIN from which the chromosomes are formed thickens and twists spirally and CHROMOSOMES are formed which become visible under a microscope.

CENTRIOLS are organelles whose main role is to form a dividing spindle during cell division, now they separate and move towards the poles of the cell.

When they reach the poles, the threads of the dividing spindle are formed between them. Chromosomes are attached to these threads.
