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 |
