The critical volume of inoculum (q.v.) required to initiate culture growth, due to the diffusive loss of cell materials into the medium. The subsequent culture growth cycle is dependent on the inoculum size, which is determined by the volume of medium and size of the culture vessel.
Industry:Biotechnology
The culture of a lateral bud and a section of adjacent stem tissue.
Industry:Biotechnology
The culture of isolated root tips of apical or lateral origin to produce <i>in vitro</i> root systems with indeterminate growth habits. Root culture was among the first kinds of plant tissue cultures, and is still largely used in the study of developmental phenomena, and mycorrhizal, symbiotic and plant-parasitic relationships.
Industry:Biotechnology
The deduction of crystal structure from analysis of the diffraction pattern of X-rays passing through a pure crystal of a substance.
Industry:Biotechnology
The degree of identity between individuals, or characters. The degree of identity between the nucleotide sequences of two nucleic acid molecules or the amino acid sequences of two protein molecules. Although sequence determination is the ultimate test of homology, useful estimates can be provided by either DNA-DNA or DNA-RNA hybridization.
Industry:Biotechnology
The degree to which tissue from one organism will be tolerated by the immune system of another organism.
Industry:Biotechnology
The delivery of a gene or genes to a fertilized egg or an early embryonic cell. The transferred gene(s) is present in all or some of the nuclei of the cells of the mature individual, including possibly the reproductive cells, and alters the phenotype of the individual that develops.
Industry:Biotechnology
The delivery of a gene or genes to a tissue or organ of an individual to alleviate a genetic disorder.
Industry:Biotechnology
The delivery of a gene or genes to a tissue other than reproductive cells of an individual, with the aim of correcting a genetic defect. <i>cf</i> somatic cell.
