WebApr 11, 2024 · To inhibit the activity of a DNA polymerase, we developed a protocol that comprised the following steps. First, the DNA polymerase was fused with a G-quadruplex binding protein (G4P) that was able to specifically recognize G-quadruplexes [29].Then, a DNA aptamer containing a G-quadruplex (G4) and a hairpin structure was bound by the … WebHairpin loops can also form in DNA molecules, but are most commonly observed in mRNA. There are many instances of the hairpin loop phenomenon among nucleic acid strands. One example of a hairpin loop is the termination sequence for transcription in some prokaryotes. Once a polymerase meets this loop, it falls of and transcription ends.
