And because of this electrostatic repulsion, that will stabilize the structure of the DNA molecule and increase its resistance to hydrolysis in the same exact way as this, the absence of this oh, on the deoxyribo sugar also increase the resistance of the DNA to hydrolysis. So these two effects increase and stabilize the structure of DNA. And so that's exactly why DNA molecules are generally much more stable than RNA molecules and are able to resist hydrolysis with a much higher potential. So we see that the fact that we have these phosphate groups does two things. It essentially dictates what that three dimensional shape of that DNA molecule, an RNA molecule is in an aqueous environment and it also increases the resistance of our DNA molecule to hydrolysis. So it makes it much less susceptible to hydrolysis.
