Dideoxynucleoside triphosphates
WebDideoxynucleoside triphosphates (ddNTPs) are used in sequencing DNA because: ddNTPs prevent further DNA synthesis once they are incorporated into the DNA sequence. ddNTPs cannot be incorporated into DNA by DNA polymerase. ddNTPs are fluorescent. ddNTPs are incorporated very efficiently into DNA by DNA polymerase. A WebJan 11, 2010 · Returning to science and the discovery of useful mutations through evolutionary analyses, these experiments show that a single L616A replacement allows a polymerase to incorporate well both 3 ′-ONH 2 and 2′-3′-dideoxynucleoside triphosphates (Fig. 2 and Fig. S7). This is an intriguing result, especially in the context of the reasoning ...

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 popular home improvement websitesWebUse of dideoxynucleoside triphosphates as base analogues and in DNA sequencing reactions.
