Our MSK physicians specialize in bone and joint imaging, spinal imaging, metabolic bone disease, and osteoporosis. Imaging techniques include plain films, CT, Ultrasound, and MRI. For diagnostic purposes, the division also performs plain films, arthrography, bone biopsies, and peripheral soft tissue lesions.
If you want to isolate plasmid DNA, you crack your cells open and carry out a miniprep, trying very hard not to get any contaminating genomic DNA in your sample.If you want genomic DNA, you crack your cells open in a different way and try to isolate as much of the stuff as possible.f you want to isolate plasmid DNA, you crack your cells open and carry out a miniprep, trying very hard not to get any contaminating genomic DNA in your sample.
Restriction Enzymes Cut DNA Molecules at Specific Sequences. To clone specific DNA fragments in a plasmid vector, as just described, or in other vectors discussed in later sections, the fragments must be produced and then inserted into the vector DNA.As noted in the introduction, restriction enzymes and DNA ligases are utilized to produce such recombinant DNA molecules.he phenomenon of transformation permits plasmid vectors to be introduced into and expressed by E. coli cells. In order to be useful in DNA cloning, however, a plasmid vector must contain a selectable gene, most commonly a drug-resistance gene encoding an enzyme that inactivates a specific antibiotic.
