Prophase definition. Prophase in both mitosis and meiosis is recognized by the condensing of chromosomes and separation of the centrioles in the centrosome. The first stage of mitosis during which the chromosomes condense and become visible the nuclear membrane breaks down and the spindle apparatus. Prophase definition prophase is the starting stage of cell division in eukaryotes.

The main occurrences in prophase are the condensation of the chromatin and the disappearance of the nucleolus. In prometaphase the nuclear envelope breaks down in many but not all eukaryotes and the chromosomes attach to the mitotic spindle. The first stage in cell division 2.

Prophase definition is the initial stage of mitosis and of the mitotic division of meiosis characterized by the condensation of chromosomes consisting of two chromatids disappearance of the nucleolus and nuclear membrane and formation of mitotic spindle.

The first stage in cell division 2. It is the stage of mitosis where the cell spends most of its time. At the beginning of prophase the membrane that surrounds the nucleus disintegrates.
