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 $\text{DNA polymerase III}$ lays down the complementary nucleotide in the $5^{\prime }$ to $3^{\prime }$ direction, and show the exonuclease activity in $3^{\prime }$ to $5^{\prime }$ direction.
