The scientific study of the chemistry of living matter.

Contributors in Biochemistry

Biochemistry

A mobile genetic element composed of repetitive DNA sequences that flank open reading frames, including one that codes for a reverse transcriptase. In contrast to transposons, which in prokaryotes ...

signal recognition particle (SRP)

Biology; Biochemistry

In the synthesis of secretory, endoplasmic reticulum (ER), Golgi apparatus, lysosomal and integral membrane proteins, a ribonucleoprotein that recognizes a signal sequence and prevents further ...

chaperone machine

Biology; Biochemistry

A multi-component system that ensures the proper folding of nascent proteins or their intracellular transport following synthesis; components include chaperones (eukaryotes) or chaperonins (from ...

molecular chaperone

Biology; Biochemistry

Enzymes and other cellular protein complexes that ensure the proper folding of nascent or improperly folded proteins. There are two classes of chaperone: the heat shock protein (hsp) 70 family and ...

electrophoresis

Biology; Biochemistry

A technique that separates charged compounds according to their mobilities in an electric field. In free zone electrophoresis the compounds are in a solution unsupported by any stabilizing matrix. In ...

rolling transcription

Biology; Biochemistry

The synthesis of RNA from a circular DNA template. Some circular DNAs, even without a promoter sequence and without assistance of a primer, may be transcribed to form concatenated circular RNA. If ...

rolling circle replication

Biology; Biochemistry

Mechanisms of DNA replication of small circular genomes, such as some viruses and plasmids, in which the template generates multiple tandem copies. One strand is nicked and serves as a primer for ...
