Circular double stranded dna
WebApr 4, 2011 · The nuclease activity of Cas3 was analysed using circular M13mp18 ssDNA or pUC57 supercoiled double-stranded plasmid DNA (Figure 3). Cas3 degraded the M13mp18 ssDNA in a concentration- and time-dependent manner (Figure 3; Supplementary Figure S5). In contrast, virtually no hydrolysis of the dsDNA occurred during the 2-h … WebCircular DNA moves on the agarose gel faster because it does not create friction (it create very little friction as compared to the liner and open circular DNA form)on the surface of …

WebRSC ATPase activity was stimulated almost equally by single-stranded DNA, double-stranded DNA, or mononucleosomes (Fig. 1C). To isolate Sth1, ... The closed circular single-stranded DNA forms were separated from other products of ligation using a 7.5% denaturing polyacrylamide gel and purified by gel extraction using standard methods. WebDNA in a closed-circular, double-stranded molecule with no net bending of the DNA axis on itself is: A) a left-handed helix. B) a mixed right- and left-handed helix. C) relaxed. D) supercoiled. E) underwound. C) relaxed. 11. It is correct to say that DNA supercoiling CANNOT: A) be induced by strand separation.
