  1. The cellular production of the protein encoded by a particular
    gene
    . The process includes
    transcription
    of
    DNA
    , processing of the resulting
    mRNA
    product and its
    translation
    into an active protein.
  2. A recombinant gene inserted into a host cell by means of a
    vector
    is said to be expressed if the synthesis of the encoded protein can be demonstrated.
