The process of making a copy of DNA is called DNA REPLICATION.

The process of making a copy of DNA is called DNA REPLICATION. Why does DNA need to be copied??? DNA contains all the information required for the function of a cell and the organisms. . Remember the base pair rule: A always pairs with T G always pairs with C
