Dideoxynucleotides are chain-elongating inhibitors of DNA polymerase, used in the Sanger method for DNA sequencing. They are also known as 2',3' because both the 2' and 3' positions on the ribose lack hydroxyl groups, and are abbreviated as ddNTPs (ddGTP, ddATP, ddTTP and ddCTP). See more The Sanger method is used to amplify a target segment of DNA, so that the DNA sequence can be determined precisely. The incorporation of ddNTPs in the reaction valves are simply used to terminate the … See more In a patented method, Tetrahydrofuran was used in a solvent containing 50 g (0.205 mols) of uridine (or, presumably, any unprotected See more • Media related to Dideoxynucleotides at Wikimedia Commons See more WebMay 24, 1990 · Inhibitory effects of four 2',3'-dideoxynucleoside 5'-triphosphates (i.e., those of 2',3'-dideoxyadenosine, 2',3'-dideoxycytidine, 2',3'-dideoxyguanosine and 2',3'-dideoxythymidine, ddATP, ddCTP, ddGTP and ddTTP, respectively) on the utilization of 2'-deoxynucleoside 5'-triphosphates (dNTPs) by terminal deoxynucleotidyltransferase …
