What is the purpose of the neutralization solution for a miniprep of plasmid DNA?
Homework Answers
Answers:
Neutralization buffer (3.0 M potassium acetate, pH 5.0) neutralizes the resulting lysate and creates appropriate conditions for binding of plasmid DNA to the silica membrane column.
This is a potassium acetate solution. The potassium acetate causes the precipitation of an SDS-protein complex as a white precipitate, consisting of SDS, lipids, and proteins. In addition, the potassium acetate neutralizes the solution allowing the renaturation of the DNA. The large chromosomal DNA is captured in the precipitate, whereas the small plasmid DNA remains in solution.

The purpose of including an ampicillin resistance gene in a plasmid into which you are cloning a piece of DNA is: This is used to prevent expression of other ampicillin resistance genes in the bacterial genome. This enables the creation of ampicillin-resistant bacteria for biomedical research. This enables selecting a bacteria colony transformed with a plasmid with a DNA insert ligated in as a means of amplifying a specified piece of DNA. This enables selecting a bacterial colony transformed with...

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...

III. Subclone the gene into plasmid, extract the plasmid DNA. 5. You know that your insert (gene of interest, GOI) is flanked by the EcoRI sites, which makes this restriction enzyme a perfect candidate to cut out your gene. You also know that the GOI has a unique BamH1 restriction site. After subcloning the PCR product into the plasmid, a purified DNA preparation of the plasmid is digested to completion with BamHI restriction endonuclease. In separate reactions, the same preparation...
