Most cells in the body have a nucleus; The nucleus contains genetic material in the form of chromosomes, coiled up lengths of DNA molecules.
Each chromosome carries a large number of genes, different genes control the development of different characteristics.
Body Cells normally have two copies of each chromosome-one from the mother and one from the father.
There are 23 pairs of chromosomes in a human cell.
Body Cells in multicellular organisms divide to produce new cells as part of a series of stages called the cell cycle. The stage when the cell divides is called mitosis.
Multicellular organisms use mitosis to grow or replace new cells that have been damaged.
