Dideoxynucleoside triphosphates
WebThe enzyme catalyzes a template-independent addition of dNTPs or of a single ddNTP to the 3'-OH ends of double- or single-stranded DNA. It accepts radioactively labeled nucleotides and nucleotides labeled with haptens, such as digoxigenin or biotin. For activity, the enzyme requires the presence of divalent metal ions, preferably Co 2+. Web(b) How a DNA sequencing reaction would be affected if the ratio of dideoxynucleoside triphosphates (ddNTPs) to deoxynucleoside triphosphates (dNTPs) were increased?
