During the purification process for recombinant DNA technology, addition of chilled ethanol precipitates out:

Options

  1. ARNA
  2. BDNA
  3. CHistones
  4. DPolysaccharides

Correct answer

B. DNA

Step-by-step solution

During the purification process for recombinant DNA technology, the RNA can be removed by treatment with ribonuclease whereas proteins can be removed by treatment with protease. Other molecules can be removed by appropriate treatments and purified DNA ultimately precipitates out after the addition of chilled ethanol.
