Assertion: Special methods are used for
transformation i.e., incorporation of recombinant
DNA into molecule.
Reason: DNA is a hydrophilic molecule. Proteins are removed by treatment with Enzyme isolated from Thermus aquaticus bacterium is used in plasmids used in genetic engineering is obtained from Which one of the following hydrolyses internal phosphodiester bonds in a polynucleotide chain? Which one of the following is used as vector for cloning genes into higher organisms?
