Detailed explanation-1: -The division cycle of most eukaryotic cells is divided into four discrete phases: M, G1, S, and G2. M phase (mitosis) is usually followed by cytokinesis. S phase is the period during which DNA replication occurs.
Detailed explanation-2: -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: -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.
Detailed explanation-4: -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-5: -In both mitosis and meiosis the replication of DNA and chromosomes occurs at the same stage.
