The purpose of the replication bubble is that it forms where replication is taking place (option A).
<h3>What is replication?</h3>
Replication is the process of producing replicas or duplicate of DNA or RNA molecules.
DNA replication is a very important process that occurs prior to cell division. During replication, the double stranded DNA is separated into two single strands.
Each copy called the leading and lagging strand becomes the template for the synthesis of new DNA strands.
However, a structure called replication bubble is a formed during the separation of two DNA strands by the helicase enzymes.
Therefore, the purpose of the replication bubble is that it forms where replication is taking place.
