Explanation:
Detailed explanation-1: -M phase (mitosis) is usually followed by cytokinesis. S phase is the period during which DNA replication occurs.
Detailed explanation-2: -Because DNA is duplicated during interphase before the cell undergoes mitosis, the amount of DNA in the original parent cell and the daughter cells are exactly the same.
Detailed explanation-3: -DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.
