R

Ribonucleic Acid (RNA) is a chemical similar to a single strand of DNA. In RNA, the letter U, which stands for uracil, is substituted for T in the genetic code. RNA delivers DNA's genetic message to the cytoplasm of a cell where proteins are made.

Ramachandran map A schematic diagram showing favorable torsion angles for a protein backbone.

Resolution A method of describing how precise a physically determined 3-dimensional structure is.

Rosetta stone method: A way of looking at the correlation of protein domains across species. Some proteins have homologs that are fused in other species, yielding clues as to the proteins with which they might interact. In addition, proteins that have been identified in particular complexes and pathways hint at the location and function of their homologs in other species.

Rotamers Conformations of a molecule differing only by rotation around single bonds.
