secondary structure of sequence macromolecule 2010-01-31: Philippe Rocca-Serra: This is a placeholder to allow work on 'nucleic acid mapping assay' in collaboration with RNAOntology group. Need to liaise with SO A quality inhering in a molecule that refers to general three-dimensional form of local segments of biopolymers such as proteins and nucleic acids (DNA/RNA). It does not, however, describe specific atomic positions in three-dimensional space, which are considered to be tertiary structure. Secondary structure was introduced by Kaj Ulrik Linderstrøm-Lang in the 1952 Lane medical lectures at Stanford. secondary structure of sequence macromolecule Wikipedia Person: Philippe Rocca-Serra physical object quality example to be eventually removed
