ex·pres·sion vec·tor

a vector (plasmid, yeast, or animal virus genome) used experimentally to introduce foreign genetic material into a propagatable host cell to replicate and amplify the foreign DNA sequences as a recombinant molecule (recombinant DNA cloning of sequences).

(eks-presh'ŭn vek'tŏr)
An agent (plasmid, yeast, or animal virus genome) used experimentally to introduce foreign genetic material into a propagatable host cell to replicate and amplify the foreign DNA sequences as a recombinant molecule (recombinant DNA cloning of sequences).

expression

1. the aspect or appearance of the face as determined by the physical or emotional state.
2. the act of squeezing out or evacuating by pressure.
3. the manifestation of a heritable trait in an individual carrying the gene or genes which determine it.

expression library
a number of different DNA molecules cloned into a single expression vector.
expression vector
