Cell Cycle/Mitosis

What is mitosis?

• one of two identical "sister" parts of a duplicated chromosome

• cell division in which the nucleus divides into nuclei containing the same number of chromosomes

• cell subtraction in which the nucleus self-destructs

• the region of the chromosome that holds the two sister chromatids together during mitosis
