Extrachromosomal DNA elements that have origins of replication for the initiation of their own DNA synthesis.
Industry:Biotechnology
Failure of disjunction or separation of homologous chromosomes or chromatids in mitosis or meiosis, resulting in too many chromosomes in some daughter cells and too few in others. Examples: In meiosis, both members of a pair of chromosomes go to one pole so that the other pole does not receive either of them; in mitosis, both sister chromatids go to the same pole.
Industry:Biotechnology
Features of organisms or molecules that are superficially or functionally similar but have evolved in a different way or contain different compounds.
Industry:Biotechnology
Female parthenogenesis; after fertilization of the ovum, the male nucleus is eliminated and the haploid individual (described as gynogenetic) so produced possesses the maternal genome only.
Industry:Biotechnology
Female reproductive organ of flowering plants, consisting of stigma, style and ovary. In some plants, one or more carpels unite to form the pistil.
Industry:Biotechnology
Fermenters in which the fermenting material is cycled between a bulk tank and a smaller tank or loop of pipes. The circulation helps to mix the materials and to ensure that gas injected into the fermenter is well distributed in the liquid. The reactors are also very useful for photosynthetic fermentations, where they allow the photosynthesizing organisms to be passed along a large number of small pipes, where the light can get to them easily, rather than inside a single volume, where only the organisms near the edges get much light.
Industry:Biotechnology
Fertilization of a plant from a plant with a different genetic makeup.
Industry:Biotechnology
Fine particles of liquid suspended in the air, such as of water in a fog chamber used for acclimatizing recent <i>ex vitro</i> transplants.
Industry:Biotechnology
Flask developed by Steward for the growth of cells and tissues in a liquid medium, in which they can be periodically submerged during rotation.
Industry:Biotechnology
Flat round dish with a matching lid, made of glass or plastic material, and used for culturing organisms. a.k.a. plates, hence the term to "plate" (q.v.) a culture.
