A Better Way to Make RNA for Physical Studies,methods. In addition, the variety of RNA sequences easily available for study is somewhat limited. Ideally, one would like a simple method to rapidly obtain multimilligram amounts of any RNA sequence desired. Although methods for the chemical synthesis of RNA have progressed rapidly in the past seve

Measurements of the binding kinetics demonstrate that Mg. binds to polymers like poly(A)

Correlation Between Crystal and Solution Structures in tRNA. Yeast tRNAPhe and tRNAAsp the Models f of yeast tRNA(Asp) (5–8). As seen in Figure 1, both molecules are folded in an L-shaped conformation, which is also found for initiator tRNAs (9,10). Since the conserved or semi-conserved residues (11) are involved in the tertiary interactions which stabilize this folding (1–10), the L-shaped struc

The Solution Structures of RNA Fragments Determined by Nuclear Overhauser Enhancement Measurements,trast, relatively few studies have appeared on RNA duplexes (5–10). This is probably due to two factors, both of which arise from the presence of the 2’-hydroxyl group in RNA. First, RNA is intrinsically more difficult to synthesize than DNA as an additional reactive group has to be protected during

Studies on 15N Labelled 5S RNA: Assignments in the Helix V Region of 5S RNA, and in the 5S/L25 Compe of ribosomal RNAs in ribosome function (for review see Noller, 1984) have stimulated renewed interest in the structural and chemical properties of RNA. Of the ribosomal RNAs only one is simple enough and small enough to lend itself to detailed physical characterization in solution, 5S RNA.

Equilibria in Ribosomal RNA Secondary Structure,As, i.e. small subunit RNA (including eukaryotic 18 S rRNA, bacterial 16 S rRNA and their mitochondrial equivalents) and large subunit rRNA (eukaryotic 28 S rRNA, bacterial 23 S rRNA and mitochondrial equivalents) can be found in a review by Noller (1984).
