question: What is the term for the multi-phase process in which the nucleus of the cell divides?
distractor3: epistasis
distractor1: cytokinesis
distractor2: mutation
correct_answer: mitosis
support: The first step is mitosis , a multi-phase process in which the nucleus of the cell divides. During mitosis, the nuclear membrane breaks down and later reforms. The chromosomes are also sorted and separated to ensure that each daughter cell receives a diploid number (2 sets) of chromosomes. In humans, that number of chromosomes is 46 (23 pairs). Mitosis is described in greater detail in a subsequent concept.
