Molecular biology

A large family of integral membrane proteins with seven transmembrane helical domains; on the extracellular surface they bind activating ligands, which induce conformational changes through to the ...

Manton-Gaulin homogenizer

Biology; Biochemistry

An apparatus for disruption of cells, especially the large quantity of bacteria or yeast that result from a fermentation, by pumping a paste of the collected cells through an orifice of adjustable ...

seven transmembrane domain protein (7TM)

Biology; Biochemistry

One of a group of structurally related long polypeptide chains which possess seven α-helical domains that span a membrane, the intervening intra- and extracellular loops which connect them, and the ...

signature sequence tag (SST)

Biology; Biochemistry

One of a set of short DNA sequences for which probes are available for the identification of a gene. As the combination of 600 to 1500 SSTs provide a unique signature for any gene, such probes can be ...

satellite DNA

Biology; Biochemistry

Short repetitive DNA sequences that occur mainly at the ends or in the center of chromosomes and are therefore suspected of serving structural roles; also, polynucleotides that are separable, on the ...

blood group substances

Biology; Biochemistry

The oligosaccharide moieties of glycoproteins that appear in many biological fluids (saliva, urine, milk) as well as on the surface of erythrocytes. These antigens, upon reaction with specific ...

molecular clock hypothesis

Biology; Biochemistry

The proposal, so far experimentally unverified, that mutations have occurred at random and at a constant frequency in all species throughout the billions of years of biochemical evolution. Successful ...
