And these super coils are known as positive super coils. And these positive super coils basically increase the stress, increase the energy of our double stranded DNA molecule. And this makes it very difficult for the helicase to actually continually unwind that double stranded DNA molecule. And so what happens is another enzyme known as DNA gyrase, which is a topo isomerase, basically creates negative super coils. It binds to our double stranded DNA and it induces negative super coils which removes the stress that are caused by the process of unwinding. So basically, DNA gyrase indirectly assists the process of DNA replication by removing the positive super coils that are formed by the process of unwinding.
