This video show DNA replication which is a fundamental process occurring in all living organisms to copy their DNA.
In a cell, DNA replication must happen before cell division. Prokaryotes replicate their DNA throughout the interval between cell divisions. In eukaryotes, timings are highly regulated and this occurs during the S phase of the cell cycle, preceding mitosis or meiosis I. DNA replication may also be performed in the laboratory in a process known as PCR.
