Cells divide for an organism to grow or reproduce, every new cell needs a copy of the DNA or instructions to know how to be a cell. DNA replicates right before a cell divides. DNA replication is semi-conservative. That means that when it makes a copy, one half of the old strand is always kept in the new strand.
