The hypothesis that a tRNA-like loop (the tag) of the genomic RNA of some viruses that functions in copying a strand of RNA into a complementary RNA or DNA strand is a relic of the part of the RNA ...

Vitamin

Biology; Biochemistry

A compound required in the diet in minute amounts; fat-soluble if soluble in organic solvents (vitamins A, D and E); water-soluble if soluble in aqueous solutions (ascorbic acid, biotin, cobalamin, ...

Regulatory subunit

Biology; Biochemistry

A part of a multimeric enzyme; a protein that binds to and inhibits the catalytic subunit unless it is bound to a regulating molecule; e.g. in the case of cyclic AMP-dependent protein kinase, the ...

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 ...

High-performance liquid chromatography (HPLC)

Biology; Biochemistry

A technique for rapid separation of solutes on a solid support, based on ion-exchange, gel permeation or partition principles; reverse-phase HPLC is when the stationary phase has a non-polar coat; ...

Multi-drug resistance (MDR)

Biology; Biochemistry

A phenomenon in which resistance that develops to one drug is manifested as resistance to many others, even those with very different structures; seen especially in chemotherapy. MDR is due to ...
