Ribose backbone

Webb9 apr. 2024 · Most recently, Brown and coworkers reported a similar additive benefit of amide backbone and locked nucleic acid (LNA) ribose modifications (AM1-LNA in Fig. 3) (Baker et al. 2024). When a single amide linkage was added to an LNA ribose in a DNA strand, the thermal stability of the modified DNA-RNA duplex increased by +3.0 °C. WebbThe three large groups of atoms attached to the ribose (the two backbone directions and the base) are pointed in different directions by the different pucker states, which means …

• Unlike double-stranded DNA, RNA is usually a single-stranded molecule (ssRNA) in many of its biological roles and consists of much shorter chains of nucleotides. However, double-stranded RNA (dsRNA) can form and (moreover) a single RNA molecule can, by complementary base pairing, form intrastrand double helixes, as in tRNA.
