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.

When this happens, the energy of the photon is transferred to the pigment molecule, thus causing the pigment to go into an electronically excited state. :)
