Replication
Replication is the process of making two identical copies of DNA.
Cells multiply by cellular division. A cell divides into two daughter cells. It is the process that allows all organisms to grow and regenerate. When a cell divides its genetic material must also be copied. This mechanism entails the separation of the two strands of the mother DNA. Two new DNA molecules are formed from each strand. This process is called semi-conservative as each new DNA molecule contains a mother strand and a new synthesised strand. This mechanism thus makes it possible to obtain two DNA molecules that are exact copies of the mother DNA. This process ensures that the genetic information of the mother cell is transmitted to the daughter cells.
