Why treat plasmid DNA with alkaline phosphatase when making a recombinant plasmid?

Sunday, November 1st, 2009

When attempting to create a recombinant DNA molecule, by inserting a foreign sequence into the vector plasmid; what is the point (and how does it achieve it) of treating the plasmid DNA with alkaline phosphatase?
I think it has something to do with the orientation of the inserted sequence, but unsure how the treatment achieves this.
thats [...]

What is the difference between the Plasmid method and Recombinant DNA in genetic engineering?

Friday, October 2nd, 2009

I have a bio paper due soon and I can’t figure out all of the methods. My teacher wanted the four major methods of genetic engineering and so far I’ve narrowed it down to the vector method, bioballistics, the plasmid method and recombinant DNA. The plasmid method and recombinant DNA sound nearly identical [...]

b. involves a vector, and DNA sequences does not
c. compares DNA fragments rather than the nucleotide order of DNA
d. makes millions of copies of DNA pieces
Please choose for th best answer and explain it..
tnx!
