Detailed explanation-1: -Prophase is the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses.

Detailed explanation-2: -The other major change in nuclear structure during mitosis is chromosome condensation. The interphase chromatin, which is already packaged into nucleosomes, condenses approximately a thousandfold further to form the compact chromosomes seen in mitotic cells (Figure 8.33).

Detailed explanation-3: -Prophase is the first phase of mitosis. During this phase, the chromosomes inside the cell’s nucleus condense and form tight structures.
