The process of copying DNA to make an identical DNA molecule before cell division.
Keep the three overall stages in the correct order: cell growth and DNA replication; mitosis; division of the cytoplasm and cell membranes.
Put the cell-cycle events in the correct order: cell growth, DNA replication, further growth, then chromosome movement during mitosis.
