Hereditary absence of pigment in an organism. Albino animals have no colour in their skin, hair and eyes. The term is also used for absence of chlorophyll in plants.
Industry:Biotechnology
Hereditary transmission dependent on the cytoplasm or structures in the cytoplasm rather than the nuclear genes; extrachromosomal inheritance. Thus, plastid characteristics in plants are inherited by a mechanism independent of nuclear genes.
Industry:Biotechnology
High-frequency recombination strain of <i>Escherichia coli;</i> in such strains, the F episome is integrated into the bacterial chromosome.
Industry:Biotechnology
High-speed centrifugation in which molecules "float" at a point where their density equals that in a gradient of caesium chloride or sucrose. The density gradient may either be formed before centrifugation by mixing two solutions of different density (as in sucrose density gradients) or it can be formed by the process of centrifugation itself (as in CsCl and Cs<sub>2</sub>SO<sub>4</sub> density gradients).
Industry:Biotechnology
Holding together; a force holding a solid to a solid or a solid to a liquid, owing to attraction between like molecules.
Industry:Biotechnology
Host plant for a grafted scion, a branch or shoot from another plant; an understock may be a fully grown tree or a stump with a living root system.
Industry:Biotechnology
Hybridization of a labelled DNA probe to RNA fragments that have been transferred from an agarose gel to a nitrocellulose filter.
Industry:Biotechnology
Hybridization of cloned DNA from one species to DNA from other organisms to determine the extent to which the cloned DNA is evolutionarily conserved.
