Now, when our helicase or helicase actually binds to the origin of replication, it unwinds that double stranded DNA. And once our two single stranded DNAs are exposed and once we unwind it, we have the single stranded binding proteins bind to each of these two single strands and that keeps those two strands apart. Now, as hellicase unwinds our double helix, that unwinding process actually introduces positive super coils. And positive super coils basically destabilize our molecule by increasing its energy. So to stabilize the unwound DNA molecule, a protein known as DNA gyrates has to bind to our molecule and introduces negative super coils which decreases the number of positive super coils and therefore stabilizes by decreasing the amount of stress that our molecule experiences. Now, once the helicase unwinds our DNA from this picture, we see that we expose these individual complementary single stranded DNA molecules.
