Elution is:

1.  separating the restricted DNA fragments on agarose gel
2.  staining the separated DNA fragments with ethidium bromide
3.  cutting out of the separated bands 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

In microinjection, the rDNA :

1. coats the micropellets and is used in biolistics to transform plant cells
2. is directly injected into the cytoplasm of a plant or an animal cell
3. is delivered in the vicinity of the plasma membrane of the cell (to be transformed)
4. is directly injected into the nucleus of an animal cell
