What is the importance of $DNA$ copying in reproduction?

(N/A) $DNA$ (Deoxyribonucleic acid) is the genetic material found in the chromosomes,which are present in the nucleus of a cell.
$DNA$ contains the information necessary for protein synthesis,and each specific type of protein leads to a specific body design.
Therefore,the $DNA$ molecule determines the body design of an individual.
During reproduction,$DNA$ copying ensures that the genetic information is transferred from parents to offspring,which maintains the continuity of species and ensures that offspring resemble their parents.
