WebJun 8, 2016 · By the way 1-5 ng of DNA per 50 ul competent cell is sufficient for transformation so I would suggest not to exceed more than 5 ul of ligation reaction. putting too much of reaction may have an ...
WebRestriction enzymes are DNA-cutting enzymes. Each enzyme recognizes one or a few target sequences and cuts DNA at or near those sequences. Many restriction enzymes make staggered cuts, producing ends with single-stranded DNA overhangs. However, … The plasmid DNA might be used in further DNA cloning steps (e.g., to build more … DNA cloning is the process of making multiple, identical copies of a particular … DNA ligase enzymes can be used to stick the cut DNA pieces back to each other … Weba. helicase unwinds the double helix. b. gyrase/topoisomerase relieves strains during uncoiling. c. helicase separates the two strands of DNA/breaks hydrogen bonds.
