Copying occurs at a localized region called the replication fork, which is a Y shaped structure where new DNA strands are synthesised by a multi-enzyme complex. Here the DNA to be copied enters the complex from the left. One new strand is leaving at the top of frame and the other new strand is leaving at bottom. The first step in DNA replication is the separation of the two strands by an enzyme called helicase.
Best Answer: I'll try to be as simple as possible.... Step 1 - Helicase unwinds the DNA so that the two strands are separated. Step 2 - Primase adds an RNA primer to each unwound DNA strand. (this is necessary in order for replication) Note that the two strands are different.One strand only needs one primer and then it can be replicated from start to finish.tep 2 - Primase adds an RNA primer to each unwound DNA strand.
