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 right, it makes sense now
thanks guys

1 Restriction enzymes cut apart random sequences of DNA.
2 "Cutting" by restriction enzymes results in DNA fragments with sticky ends.
3 DNA ligase forms weak bonds between the different DNA fragments.
4 The 2 DNA fragments from the original restriction site recombine together again, making recombinant DNA.

Explain how scientists use recombinant DNA technology to produce the drug insulin. Be sure to also explain why a gene from one organism can be expressed by another organism.

Explain how scientists use recombinant DNA technology to produce the drug insulin. Also, please explain why one organism can be expressed by another organism.
This is my own question.

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 and if they are the same then what would the fourth method be?
