Definition of Solubility differences between DNA in water and in alcohol
Check what you remember
Read the wording for your board, then hide it and explain Solubility differences between DNA in water and in alcohol in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
DNA is soluble in water but insoluble in cold ethanol, so adding cold ethanol causes DNA to precipitate out of solution.
