Molecular biology

Appearance in several forms, e.g. of a protein that is subject to tissue-specific post-translational modification, or of mRNA that is processed through alternative splice sites; also the appearance ...

clone

Biology; Biochemistry

In microbiology, a colony of cells all descended from a single ancestral cell and therefore genetically homogeneous; in molecular biology, an exact replica of a DNA fragment; cloning is the act of ...

RNase cleavage

Biology; Biochemistry

A method for detection of single base substitutions in DNA fragments. A labelled RNA probe that spans the target DNA sequence becomes susceptible to RNase A cleavage wherever there is any mismatch in ...

half-life

Biology; Biochemistry

When a property (e.g. radioactivity, enzyme activity, etc.) decreases at a rate proportional to its concentration, the time, t ½ , taken for the property to decrease to one-half its initial value; ...

quinoprotein

Biology; Biochemistry

A protein, usually of microbial origin, with a quinone prosthetic group: pyrroloquinoline quinone (e.g. methanol dehydrogenase), 6-hydrodopaquinone (topa quinone, e.g. amine oxidase) or ...

Greek key

Biology; Biochemistry

A topology found in some protein structures; antiparallel β-strands are organized into a barrel in which strands that are adjacent in the primary structure are not always adjacent in super-secondary ...

microcluster

Biology; Biochemistry

An aggregate of several (2‒10) membrane receptors that forms in response to cell stimulation; such an aggregate is a transitory state between the receptors being dispersed in the membrane and their ...
