Determination of base pairing in yeast 5S and 5.8S RNA infrared spectroscopy.
Infrared Spectroscopy was used to determine the numbers of base pairs for yeast 5S RNA and 5.8S RNA. The spectra were recorded at 20 degrees C and 50 degrees C, where tertiary interactions are assumed to be of less importance. It may be concluded that the structure of both RNAs is highly ordered and that there are large contributions of tertiary interactions. The results are compared with data derived from structural models that were proposed in the literature as well as with data previously published for prokaryotic 5S RNAs.
