pro
phase
1
the initial phase of mitosis, where chromatin condenses into visible chromosomes and the nuclear membrane dissolves, preparing for cell division
- During prophase, the duplicated chromosomes become visible under a microscope as they condense.
- The centrioles move to opposite poles of the cell during prophase to organize the spindle fibers.
- Prophase marks the start of nuclear division in mitosis, preparing the cell for chromosome segregation.
- Microtubules grow from the centrosomes during prophase to form the mitotic spindle.
- The nuclear envelope disintegrates during prophase, allowing the spindle fibers to interact with the chromosomes.
