Now following DNA replication we basically form two identical copies as shown. Now notice that these black single strands of DNA are the original strands of DNA and they are commonly known as parent strands or template strands while the blue ones are the newly synthesized strands and they are known as the door strand. So the process of DNA replication is semiconservative because each one of these copies contains one of the single strands that came from the original double stranded DNA and the other one shown in blue is the newly synthesized strand. Now how exactly do we initiate the process of DNA replication? Well, basically a special type of enzyme, a special type of protein known as DNA helicase moves very quickly along the double stranded DNA molecule and it moves until it reaches a point known as the origin of replication. So at the origin of replication the DNA helicase binds to that double stranded DNA molecule via electric forces.
