Molecular biology

An arrangement in space of the carbon-carbon bonds of the alkyl chains of a fatty acid residue of a membrane lipid. The backbone of the chain is rotated 120Â° from the trans conformation, to force ...

retrograde

Biology; Biochemistry

Having a direction opposed to the normal or usual, e.g. transport from a synapse to the cell body of a neuron or from the distal to the proximal cisternae of the Golgi apparatus; as distinguished ...

amniocentesis

Biology; Biochemistry

A procedure to obtain fetal cells during pregnancy by puncturing the womb with a needle and removing some fluid that surrounds the fetus. The procedure is used, in part, to obtain fetal cells from ...

zipper interaction

Biology; Biochemistry

The sequence of events by which an immunoglobulin G-coated lymphocyte draws the macrophage plasma membrane around it. Fc receptors on the membrane surface attach the immunoglobulin G markers and ...

photo-activated repair

Biology; Biochemistry

A mechanism for repair of DNA by reduction of thymine dimers by DNA photolyase; contrasted with dark repair, an ATP-dependent process that involves excision of the dimers, resynthesis of the sequence ...

Root effect

Biology; Biochemistry

A phenomenon in some teleost fish that allows them to generate O 2 gas in their swim bladders in the face of considerable hydrostatic pressure. The haemoglobin structure and the local secretion of ...

kringle

Biology; Biochemistry

A protein folding motif, as visualized in two dimensions, of loops formed by multiply disulphide-bridged sequences of several circulating proteins, e.g. α 2 -macroglobulin, complement component C3, ...
