Read the following statements regarding the tools and techniques of recombinant DNA technology: (A) In agarose gel electrophoresis, DNA fragments move towards the cathode under an electric field. (B) PCR is widely used for the large-scale production of recombinant proteins in industrial settings. (C) Downstream processing involves the separation and purification of the final product before marketing. (D) A simple sti

Options

  1. AOne
  2. BThree
  3. CFour
  4. DTwo

Correct answer

D. Two

Step-by-step solution

Statement (A) is incorrect because DNA fragments are negatively charged and move towards the anode under an electric field. Statement (B) is incorrect because PCR (Polymerase Chain Reaction) is used for the amplification of nucleic acids, whereas bioreactors are used for the large-scale production of recombinant proteins. Statement (C) is correct as downstream processing includes separation and purification of the product before it is ready for marketing. Statement (D) is correct because the stirrer in a simple sti
