Why does cold condition help in DNA precipitation?

Answer and explanation

Correct answer: In reducing DNA solubility

Cold conditions, especially when cold ethanol is used, reduce the solubility of DNA. DNA therefore comes out of the solution and can be collected more easily as a precipitate. Converting DNA into RNA is transcription, not DNA precipitation. Exam tip: In DNA isolation, alcohol and cold conditions are used mainly to improve DNA recovery.
