- Most of the cells in your body contain a nucleus, and most nuclei contain two copies of each choromosome. This makes them diploid cells.
- Human diploid cells contain two sets of 23 chromosomes. Body cells (all cells except sperm and egg cells) are diploid.
- To make more body cells, during growth or to replace damaged cells, body cells divide using a proces called mitosis. This process begins with choromosome makeing copies of themselves in a process called DNA replication.
- The two copies of the choromosome separate and the cell then divides. This produces two daughter cells, which are genetically identical to each other and to the parent cell.
Different kinds of reproduction
Mitosis can produce new, complete individuals in a process caled asexual reproduction. Bacteria cells often do this by splitting in half.…
