Detailed explanation-1: -Cells must replicate their DNA before they can divide. This ensures that each daughter cell gets a copy of the genome, and therefore, successful inheritance of genetic traits. DNA replication is an essential process and the basic mechanism is conserved in all organisms.
Detailed explanation-2: -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-3: -During every cell division, a cell must duplicate its chromosomal DNA through a process called DNA replication. The duplicated DNA is then segregated into two “daughter” cells that inherit the same genetic information. This process is called chromosome segregation.
Detailed explanation-4: -All cell divisions, regardless of organism, are preceded by a single round of DNA replication. For simple unicellular microorganisms such as the amoeba, one cell division is equivalent to reproduction – an entire new organism is created.
