What kind of reaction is hybridization.It is endothermic or exothermic.

Are you talking about DNA hybridization, like that which occurs in a Southern blot?

 

[qazi75]

Yes sir.DNA or any other one.But my question is that what kind of rxn is this?

 

[aroc91]

Just making sure. Hydrogen bonds occur spontaneously, so what does that tell you?

Be interested to see where you're going with this...

What do you mean by that? What I'm trying to get at is that H-bond formation is exothermic. Base paired DNA is more stable.

Edit: Well, that's not to say that there aren't spontaneous endothermic reactions, but hybridization is exothermic.
