Molecular biology

A compound synthesised from isoprene units (biosynthetically, isopentenylpyrophosphate) and recognised in products as a branched five-carbon motif. A monoterpene is composed of two isoprene units, a ...

Small G protein

Biology; Biochemistry

A class of proteins that effect intracellular structural changes via modifications of the cytoskeleton. Like other G proteins, they are active when bound to GTP, but inactive when the GTP is ...

Long interspersed nuclear element (LINE)

Biology; Biochemistry

Retrotransposons, double-stranded DNA sequences, 6-7 kb long, that occur in families of thousands of nearly identical copies which have apparently been randomly inserted into the mammalian genome. ...

Extended X-ray absorption fine structure (EXAFS)

Biology; Biochemistry

A technique for investigation of the immediate environment of metal atoms in metalloprotein crystals or solutions, e.g. Fe-S bond distances in rubredoxin; the X-ray energy is varied and the fine ...

Heteroduplex mapping

Biology; Biochemistry

An electron microscopic technique that compares sequence relationships of two polynucleotides, e.g. a spliced eukaryotic mRNA with a coding strand of DNA. Introns of the DNA strand appear as D-loops ...

Ames test (Salmonella test)

Biology; Biochemistry

A test for mutagenicity and carcinogenicity which uses specially constructed bacterial strains, by screening the effects of test compounds for their ability to produce reverse mutations that will ...

Nearest-neighbour analysis

Biology; Biochemistry

A method of analysis in which a polymer is first synthesised from a precursor labelled in a specific atom, then degraded in such a way that the labelled atom appears with the adjacent moiety and ...
