Definition
the equal division of the chromosomes into 2 genetically daughter nuclei. mitosis consist of 4 stages
-during prophase chromosomes form from condensed chomatin
-during metaphasethe chromosomes line up around the center axis of the cell
-during anaphase chromosomes are split up and chromatids are pulled to opposite ends of the cell
-during telophase a nuclear membrane form around each set of chromatids |
