Definition
a structure formed from condensed chromatin
Chromosomes consist of two identical chromatids attached at the centromere, giving them a characteristic X shape
Chromosomes occur in pairs. Human cells have 23 pairs of chromosomes, of 46 total chromosomes |

Definition
the equal division of the chromosomes into two genetically identical daughter nuclei.Mitosis consists of four stages
Prophase-chromosomes form from condensed chromatin
Metaphase- the chromosomes line up along the center axis of the cell
Anaphase- the chromosomes split up and chromatids are pulled to opposite ends of the cell
Telophase- a new nuclear membrane forms around each set of chromatids |
