Other than E.coli............ bacteria is used in recombinant DNA technology.

What are restriction enzymes ? Mention their functions in recombinant DNA technology.

Correct the underlined portion Restricition endocucleases used widely in recombinant DNA technology are obtained from Bacteriophages.

Study the following statements regarding recombinant DNA technology and select the incorrect ones. (i) Taq polymerase extends the primers using the nucleotides provided in the reaction. (ii) Antibiotic resistance genes are considered as desirable genes in recombinant DNA technology. (iii) DNA fragments are separated according to their charge only, in agarose gel electrophoresis. (iv) Transformation is a procedure through which a piece of DNA is integrated in to the genome of a host bacterium. (v) To produce higher yields of a desired protein, host cells can be multiplied in a continuous culture. (vi) Downstream processing is one of the steps of polymerase chain reaction.
