Cells must continually grow and divide in order for an organism to grow, maintain its structure, and reproduce. Cell division involves the replication, or copying, of the complete set of hereditary information. It also involves the equal distribution of the genetic material in the resulting cells. The hereditary information of organisms is contained in large molecules called deoxyribonucleic acid, DNA.
