And in the tertiary structure, we have these amino acids that are found far away from one another in that polypeptide that are interacting. So we have a bunch of these secondary structures. We have these alphaloo, or we have these alpha helixes, and we have the beta pleated sheets. And so the amino acids found on this beta pleated sheet interact with amino acids found on this beta pleated sheet. And so these bonds are part of the tertiary structure of our polypeptide. So let's suppose for argument's sake that initially by increasing the temperature, we destabilize this segment of our DNA.
