Bridged nucleic acids
WebSince starting the synthetic research on 2',4'-bridged nucleic acids in the department of bioorganic chemistry (Professor Obika) in 2009, I have been consistently advancing research related to nucleic acid chemistry. With the vigorous progress of research on the development of nucleic acid drugs targeting RNA as a therapeutic target and the ... WebDNA is a polymer of the four nucleotides A, C, G, and T, which are joined through a backbone of alternating phosphate and deoxyribose sugar residues. These nitrogen-containing bases occur in complementary pairs as determined by their ability to form hydrogen bonds between them.

However, thus far, reasons for the effectiveness of KOD DNA polymerase for such purposes have not been clearly elucidated.
A locked nucleic acid (LNA), also known as bridged nucleic acid (BNA), and often referred to as inaccessible RNA, is a modified RNA nucleotide in which the ribose moiety is modified with an extra bridge connecting the 2' oxygen and 4' carbon. The bridge "locks" the ribose in the 3'-endo (North) conformation, which is often found in the A-form duplexes. This structure provides for increased sta… WebAug 30, 2024 · Compositions and methods of use thereof for delivering nucleic acid cargo into cells are provided.
