The integration period of juvenile and reproductive stages of growth.
Industry:Biotechnology
The intensity of selection acting on a population of organisms or cells in culture. Its effectiveness is measured in terms of differential survival and reproduction, and consequently in change in the frequency of alleles in a population.
Industry:Biotechnology
The interaction of two or more dissimilar organisms where the association is advantageous to one without affecting the other(s). <i>cf</i> parasitism; symbiosis.
Industry:Biotechnology
The internal layer of cells of the gastrula, which will develop into the alimentary canal (gut) and digestive glands of the adult.
Industry:Biotechnology
The interval between the beginning of consecutive divisions of a cell. The time that it takes for a population of single-celled organisms to double its cell number. Successive generations of cells or organisms within a population are separated by a time interval called generation time. The cell regeneration time can be determined with the aid of time-lapse microcinematography.
Industry:Biotechnology
The intrinsic density which a molecule, virus or sub-cellular particle has when suspended in an aqueous solution of a salt, such as CsCl, or a sugar, such as sucrose. DNA from different species has a characteristic buoyant density, which reflects the proportion of G=C base pairs. The greater the proportion of G=C, the greater the buoyant density of the DNA.
Industry:Biotechnology
The introduction of a gene or genes into animal or plant cells, which leads to the transmission of the input gene (transgene) to successive generations. <i>cf</i> transfection.
Industry:Biotechnology
The introduction of a radioactive atom at the end of a DNA or RNA molecule. A commonly used method is to use T4 polynucleotide kinase to introduce a <sup>32</sup>P atom onto the end of a DNA molecule.
Industry:Biotechnology
The introduction of base changes - mutations - into a piece of DNA at a specific site, using recombinant DNA methods.
Industry:Biotechnology
The introduction of new gene(s) into a population by crossing between two populations, followed by repeated backcrossing to that population while retaining the new gene(s).
