NEET (UG) 2023 — Question 82
During the purification process for recombinant DNA technology, addition of chilled ethanol precipitates out
- Option A:Correct
DNA
- Option B:
Histones
- Option C:
polysaccharides
- Option D:
RNA
Answer: A
Step-by-step solution
Option (1) is the correct answer as, during isolation of the genetic material, purified DNA
ultimately precipitates out after the addition of chilled ethanol. Option (2) is not the answer as,
proteins can be removed by treatment with proteases. Option (4) is not the answer as RNA can be
removed by treatment with ribonuclease.
