DNA replication is the process by which a cell copies its DNA in preparation for cell division.
The biological process of creating two identical copies of DNA from a single original DNA molecule is known as DNA replication. All living things replicate their DNA, which is the primary mechanism for biological heredity. Semi-conservative, conservative, and dispersive replication models were proposed as possible mechanisms for organisms to repeat their DNA.
A second double strand that is exactly the same as the first is created during replication. The first step in DNA replication is to separate the dsDNA since each of the two strands in the dsDNA molecule functions as a template for a new DNA strand. A DNA helicase accomplishes this. It is crucial that each daughter cell receives an exact copy of the DNA when a cell divides. DNA replication is the process that makes this happen. Before the cell reaches mitosis or meiosis, during the synthesis phase, also known as the S phase, of the cell cycle, DNA replication takes place.
