Biochemistry

A method for amplification of a DNA fragment or a series of fragments with a single known primer-binding site. The fragment is denatured and hybridised with the primer. Extension of the primer with a ...

Kininogen

Biology; Biochemistry

A protein that contains the sequence Arg-Pro-Pro-Gly-Phe-Ser-Pro-Arg which has inhibitory activity against cysteine proteinases. A kininogen is a precursor of a kinin, which is a decapeptide or ...

Watson-Crick model

Biology; Biochemistry

The arrangement in space of two polynucleotide chains in which each chain is wrapped around the other to form two antiparallel spirals. Each strand presents to the other the bases, purine to ...

Glycosaminoglycan

Biology; Biochemistry

A subunit of a proteoglycan; an oligosaccharide that contains repeating disaccharide residues. One half of each disaccharide is an amino-sugar residue. Glycosaminoglycans include the sulphated ...

Double helix

Biology; Biochemistry

The arrangement in space of two polynucleotide chains in which each chain is wrapped around the other to form two antiparallel spirals. Each strand presents to the other the bases, purine to ...

T-cell

Biology; Biochemistry

Thymus lymphocyte, which recognises foreign proteins on the surface of other cells. The groups of T-cells include cytotoxic T-cells (CTLs; killer T-cells), which can kill the foreign cell; helper ...

Acetate rule

Biology; Biochemistry

The observation, first based on inspection of structures and later on experimentation, that many natural products appear to have been assembled from multiple acetate (acetyl-CoA and/or malonyl-CoA) ...
