During this phase the chromatin material in the nucleus condenses, coils and becomes compact, resulting in the formation of visible chromosomes. The replicated chromosomes attains an X shape and are called sister chromatids. The nucleolus disappears. The nuclear envelope disintegrates resulting in the release of the contents of the nucleus into the cytoplasm.
