Research and explain DNA replication

DNA replication is the process by which a cell copies its genetic material - the DNA - in order to eventually divide and produce two identical daughter cells. DNA replication occurs during the S phase of the cell cycle prior to cell division, and is essential for maintaining genetic continuity within a species. During this process, one strand of the double-stranded DNA molecule acts as a template, while the other is synthesized as a complementary strand, producing two identical copies of the original molecule. This is accomplished by a range of enzymatic activity, including DNA helicase, DNA polymerase, and DNA ligase, which break apart the strands of the parent double helix, copy each one, and stitch the two copies back together. DNA replication is a very accurate process, ensuring that errors are rare, and is vital for the survival of the cell and organism.
