Elution is:
1. Separating the restricted DNA fragments on agarose gel.
2. Staining the separate DNA fragments with ethidium bromide
3. cutting out of the separated band of DNA from the agarose gel and extracting them from the gel piece.
4. constructing rDNA by joining the purified DNA fragments to the cloning vector.
