DNA precipitation out of mixture of biomolecules can be achieved by treatment with:
Isopropanol
Chilled ethanol
Methanol at room temperature
Chilled chloroform
DNA -
It is a polynucleotide, in which the sugar is found as deoxyribose. Hence, the name Deoxyribonucleic acid. (DNA)
-
In a mixture of biomolecules, DNA can be precipitated by adding chilled ethanol, RNA by adding isopropanal and protein is not precipitated but is recovered from supernatent.
Option 1)
Isopropanol
Option 2)
Chilled ethanol
Option 3)
Methanol at room temperature
Option 4)
Chilled chloroform
