Summary Introduction
Introduction:
DNA replication is a process which makes an identical copy of a DNA from the original DNA molecule. The replication involves 3 steps; initiation, elongation, and termination. DNA gyrase unwinds the double helix, DNA helicase unzips the double helix, primase synthesize the RNA primer, and
