A procedure used to separate very large DNA molecules by alternating the direction of electric current in a pulsed manner across a semisolid gel.
Industry:Biotechnology
A process by which the growth of branches or petioles is abnormally pointing downward. This phenomenon is caused by the more rapid growth of the upper side. Epinasty may result from either nutritional deficiencies or irregularities at the plant growth regulator level. Not to be confused with wilting, as epinastic tissues are turgid.
Industry:Biotechnology
A process in which a matrix composed of a highly purified form of agar is used to separate larger DNA and RNA molecules.
Industry:Biotechnology
A process in which cells or micro-organisms are grown for a limited time. At the beginning of the fermentation, an inoculum is introduced into fresh medium, with no addition or removal of medium for the duration of the process.
Industry:Biotechnology
A process in which cells or micro-organisms are maintained in culture in the exponential growth phase by the continuous addition of fresh medium that is exactly balanced by the removal of cell suspension from the bioreactor.
Industry:Biotechnology
A process in which conjugation is used to transfer a plasmid vector to a target cell when the plasmid vector is not self-mobilizable. When (1) cells that have a plasmid with conjugative and mobilizing functions are mixed with (2) cells that carry the plasmid vector and (3) target cells, mobilizing plasmids enter the cells with the plasmid vector and mobilize the plasmid vector to enter into the target cells. Following tripartite mating, the target cells with the plasmid vector are separated from the other cell types in the mixture by various selection procedures.
Industry:Biotechnology
A process in which homologous chromosomes exchange material through the breakage and reunion of two chromatids. A single crossover represents one reciprocal breakage and reunion event. A double crossover requires two simultaneous reciprocal breakage and reunion events. a.k.a. recombination; recombination event.
Industry:Biotechnology
A process of enclosing a substance in very small sealed capsules from which material is released by heat, solution or other means.
Industry:Biotechnology
A process of generating starch-degrading enzymes in grain by allowing it to germinate in a humid atmosphere.
Industry:Biotechnology
A process that uses living organisms to remove contaminants, pollutants or unwanted substances from soil or water.
