And it basically acts to unwind our double stranded DNA. And since the two strands of DNA naturally want to reform those hydrogen bonds because that forms a stabilizing effect, we have a different set of proteins of enzymes known as single stranded binding proteins or simply SSB proteins that also have to bind to the individual unwound single stranded DNA molecules. And once they bind, they stabilize those molecules and keep those DNA molecules apart. So to see what we mean, let's take a look at the following picture. So, in diagram one, we basically have our two single stranded DNAs. So DNA one and DNA two and we form this double helix structure.
