Selective pressure

Biology; Biochemistry

In evolutionary theory, the effect on survival of a species of the sum of all factors, physical and behavioral, inherent and environmental; especially as an inherited trait may marginally effect ...

A graphical method for determination of a binding constant and the number of binding sites. The ratio of the amount of ligand (e.g. a hormone) that is bound (e.g. to a receptor) to the amount that is ...

Medium

Biology; Biochemistry

The solid or liquid substratum on which, or in which, cells or organ explants can be made to grow; a medium may include well defined factors such as salts, amino acids and sugars, as well as less ...

Isozyme

Biology; Biochemistry

One of two or more structural variants of an enzyme that can occur in the same individual, often relatively specific for a particular tissue, each with unique kinetic characteristics; e.g. the heart ...

Restriction fragment length polymorphism (RFLP)

Biology; Biochemistry

The variation of size of polynulceotides which are generated by restriction endonucleases and visualised by electrophoresis and Southern blotting. Changes in the normal pattern are indicative of ...

Interspersed repetitive sequence-PCR (IRS-PCR)

Biology; Biochemistry

A method for amplification of human DNA sequences in hybrid somatic cells, using primers directed at species-specific repetitive sequences: a short interspersed repeat element (e.g. Alu) sequence, a ...

Catecholamine

Biology; Biochemistry

One of a family of phenolic compounds chemically related to catechol (1,2-dihydroxybenzene), which is derived metabolically from tyrosine; the family comprises hormones and neurotransmitters, ...
