Re: Nucleic acid preservation

... the exact mechanisms of RNA degradation in frozen samples are, I'm not sure. At least in mRNA, such structures as the poly-A tail seem to be very labile and degrade spontaneously, maybe this applies to some bonds in the RNA as well (U vs. T?). Also, RNAse enzymes, which are very abundant inside ...
