DNA is a nucleic acid found in the nucleus of a cell and consisting of a polymer formed from nucleotides and shaped like a double helix & is associated with the transmission of genetic information. DNA contains the genetic material of the organism and plays a very pivotal role in the evolution of the organism. DNA regulates the entire process of cell division and DNA replication allows transfer of characteristics from parent to offspring.

1. You require DNA replication during the first phase of meiosis to produce sperm and egg cells.
2. Your body is constantly replacing old, dead cells with new cells. For cell division to occur, DNA replication must also occur.
In short, you would not exist without DNA replication.

When cells divide into daughter cells, in order to ensure that daughter cells have the same genetic makeup as their parents, DNA needs to be replicated.
