A nucleus with unreduced or doubled chromosome number that results from the failure of a meiotic or mitotic division.
Industry:Biotechnology
A number expressing the amount of some change or effect under certain conditions (e.g., the coefficient of inbreeding).
Industry:Biotechnology
A nutrient is essential when it is mandatory for growth, development and reproduction. In tissue culture, it comprises inorganic salts, including all of the elements necessary for plant metabolism; organic factors (amino acids, vitamins); usually also endogenous plant growth regulators (auxins, cytokinins and often gibberellins); as well as a carbon source (sucrose or glucose).
Industry:Biotechnology
A pair of synapsed or associated homologous chromosomes (one of maternal origin; the other of paternal origin) that have each undergone duplication. Each duplicated chromosome comprises two chromatids. Thus a bivalent comprises four chromatids.
Industry:Biotechnology
A pathway by which a metabolite is synthesized; a biosynthetic pathway.
Industry:Biotechnology
A pathway by which an organic molecule is degraded in order to release energy for growth and other cellular processes; degradative pathway.
Industry:Biotechnology
A pattern of stem elongation typical of grasses. Elongation proceeds from the lower internodes to the upper internodes through the differentiation of meristematic tissue at the base of each internode.
Industry:Biotechnology
A penicillin-derived antibiotic that prevents bacterial growth by interfering with synthesis of the cell wall.
Industry:Biotechnology
