DNA replication is the process wherein the DNA makes a copy of itself. This usually occurs during cell division. The double helix structure will be unzipped first then the hydrogen bonds will be broken down. The separated structure will then create the replication fork form. The two new strands will serve as the new, replicated DNA.
Cell replication is important because if this does not occur, this will lead to the death of the cells. It is also important that DNA will be copied so that no mutation will occur as new cells are formed. This will ensure that people will be getting healthy cells.
