Notes:
The melting characteristics of unfractionated yeast s-RNA in neutral aqueous solution have been examined by high-resolution proton magnetic resonance spectroscopy. These studies indicate that the bases of s-RNA become rotationally activated at lower temperatures than their associated ribose units. These observations, as well as the recently determined base sequence of an alanine-specific s-RNA, suggest that base complementarity may not be the primary determinant in the stabilization of the secondary structure of s-RNA. In addition, evidence for exchange of C8-protons of purine bases of s-RNA with D2O was obtained at temperatures above 70°C.
