DNA replication is the process by which two copies of a DNA molecule is produced from one.
The creation of a DNA copy is essential to produce organisms which are similar to their parents. As copying of DNA brings some variations each time, the surviving cells are similar to parent cell but subtly different from each other. This tendency for variation during reproduction brings variations among the individuals of the same species.
