What is the role of alcohol in extracting DNA? 1.DNA is a polar molecule with an overall negative charge, and as such is not soluble in alcohol, and therefore precipitates.  2.DNA is a polar molecule with an overall positive charge, and as such is not soluble in alcohol, and therefore precipitates.  3.DNA is a non polar molecule with an overall negative change, and as such is soluble in alcohol, and therefore precipitates.  4.DNA is a polar molecule with an overall positive change, and as such is soluble in alcohol, and therefore precipitates.
