1. Agrobacterium tumefaciens
Agrobacterium tumefaciens is a Gram-negative bacterium found in soil which causes crown gall disease in plants (which causes tumor s to form at the crown and at the junction of the root and stem). The tumors are caused by the Ti plasmid in the bacterium; this plasmid is being heavily researched by plant genetic engineers because it is a useful way to introduce new genes into a plant cell.

2. Agroinfection
A method of using the t-DNA of plasmid s to infecting plant cells with DNA from a plant virus .

3. Alkaline phosphatase
An enzyme which hydrolyzes phosphate ester s and works best in the pH range of 9 to 11; it catalyzes the removal of phospate groups near the 5' end of linear DNA strands such as restricted plasmid molecules. This enzyme is typically obtained from calf intestinal tissue or E. coli and is used widely in gene cloning experiments and in enzyme-antibody conjugates in ELISA and immunochemistry .

4. Autonomously replicating sequence (ARS)
This is a chromosomal sequence that allows plasmid s to replicate on their own in yeast .

5. Babesiasis (babesiosis, piroplasmosis)
A parasitic disease affecting mammals which is caused by protozoa from the genus Babesia of the order Piroplasmida and is transmitted by ticks. The Babesia protozoa feed on the blood of mammals. Symptoms include high fever, anemia , and red urine (hemoglobinuria).

6. Bacterial conjugation
The process of transferring a certain plasmid of DNA known as the F plasmid (or sex plasmid) from bacteria individuals who have it (known as "males") to bacteria individuals who do not already have it (known as "females") by way of direct contact between the bacteria individuals called a conjugation bridge . Once transfer is completed, the female individual becomes a male individual and both parties have a copy of the F plasmid.

7. Bacterial transformation
A genetics lab procedure where bacteria are induced to accept and incorporate into their genome foreign pieces of cell -less, isolated DNA , often in the form of a plasmid . The DNA to be introduced usually contains a selectable marker so that the bacteria which successfully incorporate the DNA can be selected for.

8. Bacteriocinogen
A plasmid , or ring of DNA , found in certain bacteria which controls the production of bacteriocin , a substance that the bacteria can use to kill closely-related strains of other bacteria without rupturing their cell membrane s.

9. C600
A strain of the bacteria Escherichia coli which is used in genetics experiments as a host for foreign plasmid s that have been clone d.

10. Chi structure
The name for the X-shaped structure which forms during the recombination process between two plasmid s, or circular pieces, of DNA . The Greek letter chi resembles this structure.
