Glossary of terms The molecular building blocks for proteins.
Technology for working with biological systems. Includes genetic
engineering, human and veterinary medicine, crop and animal
breeding, diagnostics, pharmaceuticals, forensics, etc. Bt
(Bacillus thuringiensis) A soil bacterium that produces
insecticidal proteins. The Bt protein has been introduced into
various crops as a built-in insecticide. A linear structure in
the nucleus of plants and animals that is visible in light
microscopy when stained. The chromosome is a single, long,
linear molecule of DNA and associated proteins. Deoxyribonucleic
acid, the molecule that stores genetic information. Composed of
two complementary strands. An “event” in genetic engineering is
the insertion of a particular piece of foreign DNA into the
chromosome of the recipient. Insertion occurs in random
locations, so each event is unique. The event can affect how a
gene is expressed in the organism. Once an event occurs, the
transgene can be passed to the next generatio
