Adrenergic

Biology; Biochemistry

Responsive to the adrenal medullary hormone, i.e. adrenaline (epinephrine), and by extension responsive to other catecholamines. β-Adrenergic responses are those that result in the intracellular ...

The point of attachment of two chromatids during meiosis that results in crossing-over, which is the exchange of a region of one chromosome, from an end to the chiasma, with the homologous region of ...

Energy spectrum

Biology; Biochemistry

A profile of the energy of the emissions from a radioactive atom; the fraction of total emissions from the decay of a radioactive atom, e.g. the β-emissions of 14 C as a function of the energy of ...

Fluorescence photobleaching recovery

Biology; Biochemistry

A technique to measure the mobility of membrane lipids by destruction of fluorophore-tagged molecules in a very small area of a membrane and measurement of the rate at which new molecules migrate ...

Shine-Delgarno sequence

Biology; Biochemistry

A polynucleotide sequence of prokaryotic mRNA that is complementary to, and therefore base-pairs with, a sequence at the 3'-end of bacterial 16S rRNA, which function to position the initiator codon ...

Transamidation

Biology; Biochemistry

The substitution of one amino compound for another in an amide linkage, e.g. the cross-linking of fibrin by the displacement of NH 3 from glutamine residues by an ε-amino group of a lysine residue ...

Hybrid hybridoma

Biology; Biochemistry

A cell that produces antibodies with dual specificity because it is a fusion of two hybridomas, and therefore produces immunoglobulins characteristic of each parent cell and hybrids that display one ...
