Biochemistry

An insertion or deletion in the coding sequence of a gene which, because it is shared by phylogenetically distant species, is thought to be evolutionarily conserved and therefore can serve to trace ...

Arginine fork

Biology; Biochemistry

A specific kind of interaction between an RNA and an RNA-binding protein in which the two equivalent guanidinium nitrogens of an arginine residue interact with adjacent phosphates of a ...

SOS repair

Biology; Biochemistry

An error-prone DNA repair process induced in response to ultraviolet-light-induced mutagenesis. In the face of pyrimidine dimerization, it allows for continued DNA resynthesis with relaxation of the ...

Mole percent excess

Biology; Biochemistry

A quantitative measure of the concentration of a stable isotope, analogous to the specific radioactivity of a radioisotope; the enrichment of that isotope, as a percentage of all isotopes, over and ...

Chemiluminescence

Biology; Biochemistry

The light emitted by an exergonic chemical reaction; contrasted with photoluminescence (fluorescence or phosphorescence), which is the light emitted as a fluorophore falls to a lower energy state ...

Di-

Biology; Biochemistry

A prefix derived from the Greek for two; also the form of the prefix dia- used before a vowel. In organic chemistry, used to denote twice the usual proportion of an element or other component; bi- ...

Alpha (α)-helix

Biology; Biochemistry

A secondary structure in proteins; the right-handed helical folding of a polypeptide such that amide nitrogens share their hydrogen atoms with the carbonyl oxygens of the fourth amide bonds towards ...
