DNA replicates in order for cells to divide, withy a parent cell divides giving each daughter cell the full DNA string in each nucleus. Without cell division, an organism cannot grow into a plant, a human or an animal. D... More »

Many enzymes are involved in DNA replication, including DNA helicase, DNA polymerase, topoisomerase, DNA gyrase, DNA ligase, primase and telomerase. Replication is a complex process with many steps, all of which require ... More »

Replication is the process by which DNA is copied during mitosis and meiosis; transcription is the process by which RNA is synthesized with DNA as a template. These processes have some fundamental similarities, but they ... More »

DNA replication takes place in the nucleus of eukaryotic cells and in the cytoplasm of prokaryotic cells, HowStuffWorks states. Reference explains that prokaryotes are organisms without a nucleus. More »

DNA replicates so that new cells can be created; the replication allows old or damaged cells to create replacement cells that support the life of the organism. DNA replication permits the new cells to have the same genet... More »

DNA polymerase II is a type of DNA polymerase: a category of enzymes that synthesize identical copies of existing DNA, allowing dividing cells to pass this genetic information on to their daughter cells. DNA polymerase I... More »

The primary purpose of DNA is to store hereditary information within the cells of all living things. It is a molecule that encodes the genetic instructions used in the development and functioning of all known living orga... More »
