Answer: basic 3. In general, the division of the cell, called _______, follows immediately upon mitosis.
Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA. 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.The replication process relies on the fact that each strand of DNA can serve as a template for duplication.eplication 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.
