Biochemistry

The unequal distribution of a diffusible ion across a semi-permeable membrane when an impermeable electrolyte, such as a protein, is also present on one side; e.g. a solution of an anionic protein ...

G-protein

Biology; Biochemistry

GTP-binding protein; one of a superfamily of proteins that function in, for example, signal transduction (e.g. the G-protein associated with the b-adrenergic receptor), polymerization (e.g. tubulin), ...

Jumping PCR

Biology; Biochemistry

A technique for reconstruction and replication of randomly damaged double-stranded DNA, e.g. that found in mummified tissues or museum samples. In the first PCR cycle each primer is extended until a ...

Comparative map

Biology; Biochemistry

An application of the comparative mapping of genes and other genetic markers in the genomes of several mammalian species to the localization to a specific chromosomal locus of a gene, in particular ...

Cyanobacterium

Biology; Biochemistry

Cyanobacteria (also known as blue-green algae, blue-green bacteria, and Cyanophyta) is a phylum of bacteria that obtain their energy through photosynthesis. The name "cyanobacteria" comes from the ...

Loss of heterozygosity (LOH)

Biology; Biochemistry

A test for chromosomal changes in tumour DNA and the theory that some tumours arise from inactivation of both alleles for an anti-oncogene. Heterozygotes, who already have one mutation, are most ...

Molecular resonance force microscopy (MRFM)

Biology; Biochemistry

A technique similar to atomic force microscopy, which, in theory, can detect and map magnetic resonance in paramagnetic nuclei of macromolecules. The MRFM resonator probe, mounted on a flexible ...
