DNA replication
Explanation:
DNA replication is the process whereby the genetic material (DNA) duplicates itself into two identical copies. This process must occur prior to any cellular division (meiosis or mitosis) in order to ascertain that each daughter cell gets an even and correct amount of DNA.
The process of DNA replication begins with the unwinding of the double stranded DNA molecule into two single strands of DNA. One strand called leading strand runs from 3'-5' while the other strand runs from 5'-3'. However, DNA replication proceeds in the 5'-3' direction.
