Molecular biology

Literally, outside of the germ line; therefore characteristics passed from cells to progeny without altering germ line DNA, e.g. genetic imprinting and tissue-specific development in eukaryotes and ...

mobile carrier

Biology; Biochemistry

A proposed mechanism of membrane transport similar to the mobile barrier mechanism, but in which the porter is imagined to be a revolving door that accepts one (uniport) or two (symport) solutes, or ...

CFTR

Biology; Biochemistry

CFTR (cystic fibrosis transmembrane conductance regulator) is a member of the ATP-binding cassette (ABC) superfamily of proteins. CFTR regulates chloride transport in epithelial cells. Mutations in ...

tocochromanol

Biology; Biochemistry

Any tocopherol or tocotrienol compound, for example, α-tocopherol, γ-tocopherol, δ-tocopherol, α-tocotrienol, γ-tocotrienol, etc. These are lipid-soluble molecules that belong to the group of vitamin ...

heat-shock consensus element (HSE)

Biology; Biochemistry

A 14 base pair polynucleotide sequence upstream from structural genes for heat-shock proteins, required for optimal expression. A somewhat longer polynucleotide sequence that includes flanking ...

siderophore

Biology; Biochemistry

A low-molecular-mass compound that binds to ferric ions and facilitates their absorption by the micro-organisms that produce them; e.g. enterobactin, the catechol derivative of some bacteria, and ...

exon trapping

Biology; Biochemistry

A method for recovery of exons from random segments of cloned genomic DNA that depends upon passage through a retroviral life cycle; non-viral genomic DNA is spliced and may then be excised as cDNA ...
