Cohesive end cloning
Did you know?
WebCloning or subcloning a DNA fragment into a plasmid vector is a routine procedure in modern recombinant DNA technology. After restriction or modification with appropriate enzyme to generate compatible termini, the insert DNA and the linearized plasmid molecule are joined by ligase. Web5. Treatment with R.E produces sticky ends after ligation with target DNA. Sticky ends are desirable for DNA cloning experiments. One drawback is R.E. used to generate cohesive end in the linker will also cut foreign DNA at internal sites. Solution to the problem is to choose another restriction enzyme or to methylate internal restriction sites ...
WebMay 9, 2024 · So standard cohesive end ligation is not possible since the 3' end is incompatible with the vector sticky end. So I've tried variations of blunt end ligation by digesting my... WebCosmids are plasmids that incorporate a segment of bacteriophage λ DNA that has the cohesive end site ( cos) which contains elements required for packaging DNA into λ particles. Under apt origin of replication (ori), it can replicate as a plasmid It is normally used to clone large DNA fragments between 28 and 45 Kb. [6]
WebThe ends of the vector should not be able to re-ligate because either they are incompatible (e.g., digested with two restriction enzymes that do not generate compatible ends) or the 5´ phosphate group has been removed in a dephosphorylation reaction (e.g., blunt ends treated with rSAP).
