WebIn a circular, double stranded DNA that had four HindIII cleavage sites and three EcoRI sites, how many fragments would you expect if you digested the DNA with both HindIII and EcoRI The gel matrix itself can determine resolution. WebInserting DNA into a vector Once the required fragment of DNA containing the gene that has been cut from the DNA has been synthesized The next step is to transfer it to the host cell by joining it in the carrying unit known as a vector. Plasmids contain small single circular pieces of double-stranded DNA, and they occur naturally in a bacterial cell. The …

In this state, its writhe W = 0. Since L = T + W, in a relaxed state T = L. Thus, if we have a 400 bp relaxed circular DNA duplex, L ~ 40 (assuming ~10 bp per turn in B-DNA). Then T ~ 40 .
