Industry:Biotechnology
A locus that affects a quantitative trait. The plural form (quantitative trait loci) is also abbreviated as QTL.
Industry:Biotechnology
A low molecular weight substance that binds very tightly to iron. Siderophores are synthesized by a variety of soil micro-organisms to ensure that the organism is able to obtain sufficient amounts of iron from the environment.
Industry:Biotechnology
A low-molecular-weight compound or a physical agent that is bound by a repressor so as to produce a complex that can no longer bind to the operator; thus, the presence of the inducer turns on the expression of the gene(s) controlled by the operator.
Industry:Biotechnology
A lyophilic colloid that has coagulated to a rigid or jelly-like solid. It is used for the electrophoretic separation of nucleic acids or proteins, and for encapsulation.
Industry:Biotechnology
A macromolecule composed of phosphoric acid, pentose sugar, and organic bases. The two nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), are made up of long chains of molecules called nucleotides (q.v.). They were first isolated as part of a protein complex in 1871, and were separated from the protein moiety in 1889.
Industry:Biotechnology
A major ecological community or complex of communities, extending over a large geographical area and characterized by a dominant type of vegetation.
Industry:Biotechnology
A malignant tumour derived from epithelial tissue, which forms the skin and the outer cell layers of internal organs.
Industry:Biotechnology
