Detailed explanation-1: -During the S phase of the cell cycle, DNA replication occurs at the interphase . There are four stages in the cell cycle i.e. G1, S, G2, and M. DNA replicates before actual cell division so that identical set of the genome of the parent cell is received by each daughter cell.
Detailed explanation-2: -DNA replication occurs during the S phase (the Synthesis phase) of the cell cycle, before mitosis and cell division. The base pairing rules are crucial for the process of replication. DNA replication occurs when DNA is copied to form an identical molecule of DNA.
Detailed explanation-3: -Before mitosis occurs, a cell’s DNA is replicated. This is necessary so that each daughter cell will have a complete copy of the genetic material from the parent cell.
Detailed explanation-4: -Before a cell can enter the active phases of mitosis, however, it must go through a period known as interphase, during which it grows and produces the various proteins necessary for division.
Detailed explanation-5: -In both mitosis and meiosis the replication of DNA and chromosomes occurs at the same stage.
