What is the importance of $DNA$ copying in reproduction ?
$DNA$ (Deoxyribonucleic acid) is the genetic material found in the chromosomes, which are present in the nucleus of a cell. The $DNA$ is the information site for making proteins and each specific type of protein leads to a specific type of body design.
Thus, it is the $DNA$ molecule that determines the body design of an individual. Therefore, it can be concluded that it is the $DNA$ that gets transferred from parents to offsprings and makes them look similar.
