Answer is prophase.
Prophase is the first phase of mitosis (a method of cell division). 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.
