Which phase of mitosis is characterized by the condensation of chromatin?

Prophase is the phase of mitosis during which chromatin, which is the relaxed form of DNA within the nucleus, condenses into distinct chromosomes. This condensation is crucial because it allows the genetic material to become more compact and easier to manage as the cell prepares for division. During prophase, the nuclear envelope begins to break down, and the mitotic spindle starts to form, making it essential for the chromosomes to be organized and accessible for proper segregation. The process of condensation ensures that the chromosomes can be moved efficiently to opposite poles of the cell, facilitating a successful mitotic division.
