A or B: RNA-DNA hybrids, key intermediates in gene regulation, were classified by pulsed electron-electron double resonance (PELDOR) in combination with CD spectroscopy into two classes, interpreted as A- and B-like structures. RNase H1 cleavage of these hybrids is in full agreement with these assignments, cleaving the hybrids with A-like geometry preferentially. This combined analytical approach allows the interpretation and eventually the design of more easily cleavable hybrids as needed for the antisense technology.
