Refers to a wide range of techniques used to study, improve, create, or manipulate the genetic material
Used to seperate the chemical constituents or the disrupted cells on the basis of weight
You use these chemicals to recognize specific short nucleotide sequences in the DNA and cut the DNA molecule at that site.
