Hi, I'm Michael Maidaa, and this what enzyme uncoils DNA so it can be replicated. In this question we're talking about eukaryotic DNA replication. We must remember that there are a bunch of different enzymes that are part of this process, and right now we'll just be discussing one of those. The one that specifically uncoils the DNA. The name of this enzyme is helicase. So how exactly does helicase break apart the DNA so that it can be replicated? It breaks the H-bonds or hydrogen bonds that are connecting the DNA molecule. This process requires ATP. So it's ATP driven. Here I will be drawing a DNA molecule, a simple sketch. Normally there are hydrogen bonds holding it all together. In this process, helicase will come through and break apart these strands. By separating these strands, it allows other enzymes to come in and perform the replication process. I'm Michael Maidaa, and this has been what enzyme uncoils the DNA for replication.
