    Note

    Biologists use the verb for a gene's whole route to an effect: for a protein-coding gene, the DNA is copied into messenger RNA, and that RNA is read into protein. Either the gene or its product can be the object, so a cell expresses a gene and also expresses the protein it codes for. A gene that is not expressed is present in the cell but silent.
