You are trying to perform in vitro DNA replication on a small circular piece of DNA. You have DNA polymerase, Primase, Helicase, DNA ligase and all of their accessory proteins. You can get DNA replication to initiate but it never goes for very long without stopping. You visualize your small piece of DNA under an electron microscope and notice that after the initiation of replication, it looks all knotted up. What enzyme can you add to remedy this problem?
