Industry:Biotechnology
Room for maintaining cultures and often in a controlled environment of light, temperature and humidity. <i>cf</i> growth cabinet; incubator.
Industry:Biotechnology
Root system in which both primary and lateral roots have approximately equal diameters. Opposite is <i>tap root.</i>
Industry:Biotechnology
Root system in which the primary root has a much larger diameter than the lateral roots. Opposite: fibrous root.
Industry:Biotechnology
Rotating apparatus with a platform on which, containers can be shaken, such as Erlenmeyer flasks containing cells in liquid nutrient medium.
Industry:Biotechnology
Selection of a clone from a large number of essentially random starting points, rather than isolating a natural gene or making a carefully designed artificial one. Molecules which are more similar to those needed are selected, mutated to generate new variants, and re-selected. The cycle proceeds until the required molecule is found. The advantage of the system is that the selection is from a vast number of possibilities.
Industry:Biotechnology
Selection of cells via a gene encoding a product that enables only the cells that carry the gene to grow under particular conditions. For example, plant and animal cells that express the introduced Neo<sup>r</sup> gene are resistant to the compound G418, while cells that do not carry the Neo<sup>r</sup> gene are killed by G418. a.k.a. positive selection; <i>see also</i> positive selectable marker.
Industry:Biotechnology
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.
