Genetic engineering

negative selection

Biotechnology; Genetic engineering

Selection of individuals that do not possess a certain character. A method by which growing cells that do not carry a DNA insert integrated at a specific chromosomal location are selected.

autotrophic

Biotechnology; Genetic engineering

Self-nourishing organisms capable of utilizing carbon dioxide or carbonates as the sole source of carbon and obtaining energy for life processes from radiant energy or from the oxidation of inorganic ...

extrachromosomes

Biotechnology; Genetic engineering

Self-replicative genetic elements separate from main chromosome(s) of a cell. This definition usually excludes viruses, but the division is somewhat arbitrary. In bacteria, plasmids are the principal ...

pH-electrode-based sensor

Biotechnology; Genetic engineering

Sensor in which a standard electrochemical pH electrode is coated with a biological material. Many biological processes raise or lower pH, and the changes can be detected by the pH electrode.

oxygen-electrode-based sensor

Biotechnology; Genetic engineering

Sensor in which an oxygen electrode - a standard electrochemical cell which measures the amount of oxygen in a solution - is coated with a biological material which generates or absorbs oxygen. When ...

centrifugation

Biotechnology; Genetic engineering

Separating molecules by size or density using centrifugal forces generated by a spinning rotor. G-forces of several hundred thousand times gravity are generated in ultracentrifugation.

disjunction

Biotechnology; Genetic engineering

Separation of homologous chromosomes during anaphase I of meiosis; separation of sister chromatids during anaphase of mitosis and anaphase II of meiosis. As soon as the sister chromatids have ...
