All the contents of a cell, including the plasma membrane,but not including the nucleus.

The genetically programmed repression of transcription. Silencing may be the net effect of regulatory events that increase transcription and those which repress it (the analogue model), or it may be ...

Acetogenin

Biology; Biochemistry

A compound derived from acetyl units donated by acetyl- and/or malonyl-CoA units, assembled into a non-reduced polyketide, i.e. with the carbonyl groups intact, often, then, cross-linked by aldol ...

Depside

Biology; Biochemistry

An ester of two or more derivatives of orsellinic acid (1,2-dihydroxy-5-methylbenzoic acid). A depsidone is a depside in which the aromatic subunits are additionally coupled to each other by an ether ...

Northern blotting

Biology; Biochemistry

By analogy with Southern blotting, a technique for detection of specific RNA molecules; RNA from a cell is denatured and separated by slab gel electrophoresis, then blotted on to a sheet of ...

Holliday model

Biology; Biochemistry

A conceptualization of general genetic recombination of newly replicated DNA during meiosis. An endonuclease nicks one strand of each of the two daughter duplexes at homologous sites which permits ...

Competitive binding assay

Biology; Biochemistry

A technique for assaying a substance by observing how effective it is, compared with standards, in displacing a fixed amount of the labelled (often radiolabelled) material from a binding site of ...
