DNA replication plays a critical role in the increase and renewal of cells. developing organisms are constantly creating new cells as they turn into a bigger frame. And over time, some cells can become broken, develop old, or die. To hold your frame functioning well, it is important that these cells are quickly replaced with new ones. Cells accomplish this renewal and boom via the method of the cellular department, wherein one cell splits in 1/2 to shape two new cells. So as for a cell to divide, it has to first make a copy of its own DNA, which is the genetic code it wishes to characterize nicely. It is very important that your DNA is replicated accurately, with new cells receiving an actual replica of your genetic series.
