DNA replication is the fundamental process that happens in every living organism. It's the basis of biological inheritance.DNA replication is needed because of mitosis. Mitosis is the creation of new cells. New cells need DNA, therefor the new DNA is put in the new cells. Without the replication of DNA new cells wouldn't be able to be made which would be impossible for living organisms to survive.
