During prophase, what happens to the nuclear envelope?

Explanation:
During prophase, the nuclear envelope dissolves. This breakdown frees the chromosomes so spindle fibers can attach to kinetochores and organize the chromosomes for their upcoming separation. At the same time, chromosomes condense and the nucleolus disappears, signaling the cell is transitioning from chromatin to distinct chromosomes. The envelope doesn’t thicken or stay intact, and envelope duplication isn’t part of prophase.
