'''NMR SOLUTION STRUCTURE OF A PEPTIDE NUCLEIC ACID COMPLEXED WITH RNA'''
===NMR SOLUTION STRUCTURE OF A PEPTIDE NUCLEIC ACID COMPLEXED WITH RNA===




==Overview==
<!--
Peptide nucleic acids (PNA) incorporating nucleic acid bases into an achiral polyamide backbone bind to DNA in a sequence-dependent manner. The structure of a PNA-ribonucleic acid (RNA) complex was determined with nuclear magnetic resonance methods. A hexameric PNA formed a 1:1 complex with a complementary RNA that is an antiparallel, right-handed double helix with Watson-Crick base pairing similar to the "A" form structure of RNA duplexes. The achiral PNA backbone assumed a distinct conformation upon binding that differed from previously proposed models and provides a basis for further structure-based design of antisense agents.
The line below this paragraph, {{ABSTRACT_PUBMED_7519361}}, adds the Publication Abstract to the page
