1. Abiogenesis
The scientific study of how life originally arose on the planet, presumably from nonliving things and the presence of nonliving organic matter.

2. Abiogenesis
Early theory that held that some organisms originated from nonliving material.

3. Adaptation
Tendency of an organism to suit its environment; one of the major points of Charles Darwin's theory of evolution by natural selection : organisms adapt to their environment. Those organisms best adapted will have a greater chance of surviving and passing their genes on to the next generation.

4. Additive genetic variance
The proportion of genetic variation that is the summation of the effect of all individual genes influencing a trait.

5. Agenesis
A condition in which a part of the body (such as an organ or a tissue) doesn't completely develop or fails to develop at all.

6. 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.

7. Amphotropic packaging cell lines, amphotropic virus
Clonal entities that express genes or act as viral vector s that infect cell lines to stably infect and then express genes of choice.

8. Anaphylactogenesis
The process of causing or creating anaphylactic shock .

9. Angiogenesis
The formation of new blood vessels. This occurs normally during the development of the embryo , but can also occur abnormally around malignant tumor s.

10. Antibiotic resistance genes
Gene s in a microorganism which confer resistance to antibiotic s, for example by coding for enzyme s which destroy it, by coding for surface protein s which prevent it from entering the microorganism, or by being a mutant form of the antibiotic's target so that it can ignore it.
