Full Answer

The cells in the human body only undergo division when their DNA has been fully duplicated. Once the second string of DNA has been assembled, the cell divides into a pair of cells with roughly equal amounts of cytoplasm and organelles. This process leaves the cells of the body with full, identical complements of genes. Only germ-line cells undergo partial separation and carry 23 chromosomes.
