Explanation: 

Detailed explanation-1: -The end of prophase is marked by the beginning of the organization of a group of microtubules to form a spindle. In later stages of mitosis, the chromatids will attach to this spindle and pull apart, ensuring that each daughter cell has an identical and complete set of chromosomes.
