A wild relative of a plum tree contains a gene that codes for a protein that helps the plant resist a fungal disease.
Scientists want to transfer this gene into plum plants.
State the missing term in each of stages 1-3 in this sequence.
| Stage | Description |
|---|---|
| 1 | __________ cuts the required gene from donor DNA. |
| 2 | The gene and an opened plasmid have complementary __________. |
| 3 | __________ seals the gene into the plasmid to form a recombinant plasmid. |
State two steps used after the recombinant plasmid has been introduced into recipient cells to obtain plum plants containing the transferred gene.
