Locked Nucleic Acid - LNA™
... Locked Nucleic Acids (LNA™) are a class of nucleic acid analogues in which the ribose ring is “locked” by a methylene bridge connecting the 2’-O atom with the 4’-C atom (see structure below). LNA™ nucleosides contain the six common nucleobases (T, C, G, A, U and mC) that appear in DNA and RNA and th ...
