Explain how scientists can isolate plasmid DNA despite the fact that both genomic and plasmid DNA are made of the same type of molecules (nucleic acids).
Homework Answers
After resuspension and cell lysis (removing cell wall and protecting both the DNAs from damaging by DNases) of the bacterial culture, the sample is neutralized by potassium acetate solution. In this solution plasmid DNA gets renatured and dissolved in the solution whereas genomic DNA gets denatured and precipitated and thus filtered out of the solution by centrifugation. Now the dissolved plasmid DNA is precipitated by ethanol or purified with phenol-chloroform mixture. This precipitated plasmid DNA is filtered out for study.

You isolate plasmid DNA from bacteria (Questions 7-10) 7) A plasmid is an extrachromosomal circular DNA frequently found in prokaryotes. Aside from being smaller, how is it different from the prokaryotic genome? You place equal amounts of plasmid DNA in 4 different tubes and incubate the DNA with increasing amounts of the enzyme topoisomerase I for 1 hour (0 enzyme units 0.25 enzyme units, 0.5 enzyme units and 1 enzyme unit). You then analyze the plasmid...

RECOMBINANT DNA: PLASMID VECTOR engineering is the direct manipulation of an organism's DNA using nology. To begin the recombinant DNA process, scientists must first ide at codes for the production of the protein they want to manufacture. One is to go backwards from the amino acid sequence of the desired protein to ide sequence of the gene. After scientists have identified the gene, they m it. Restriction enzymes or endonucleases from bacterial cells are key in th ia produce restriction...
