| genes, reporter | Genes whose expression is easily detectable and therefore used to study promoter activity at many positions in a target genome. In recombinant DNA technology, these genes may be attached to a promoter region of interest. (12 Dec 1998) |

| reporter gene | <molecular biology> A gene that encodes an easily assayed product (e.g. CAT) that is coupled to the upstream sequence of another gene and transfected into cells. The reporter gene can then be used to see which factors activate response elements in the upstream region of the gene of interest. (18 Nov 1997) |
