Question

Why do we add isopropyl alcohol to the tube of DNA, and what is the result?

Answer 1

Answer:

To achieve precipitation of the DNA.

Explanation:

Isopropyl alcohol makes the DNA sediment. The DNA, once out of the solution, becomes visible, as it clumps.

The result of adding isopropyl alcohol is the precipitation or sedimentation of DNA when DNA becomes like a visible thread with the help of alcohol and salt. The precipitation of DNA is important because it removes the dirt from DNA.
