DNA replication
After the process of DNA replication occurs, each daughter cell receives an exact copy of the parent cell's DNA.
DNA replication is a biological process by which a DNA molecule divides to produce two copies of itself during cell division. DNA replication takes place in all living organisms. During DNA replication, an enzyme known as helicase separates the double helix structure of the DNA molecule into two separate strands which serve as templates for making the new strands of DNA.
