Most of the time, a gene product is a protein. Sometimes gene products can also be an RNA molecule. In forward genetic analysis, we can't formally tell if a gene product is has an easily observed function and that can be used to indirectly measure the level of transcriptionplugin-autotooltip__default plugin-autotooltip_bigRNA transcription: the process of RNA polymerase using the DNA sequence of a gene as a template to form an mRNA (in prokaryotes) or pre-mRNA (in eukaryotes). In most cases, “transcription” implies RNA transcription. determined by a promoterplugin-autotooltip__default plugin-autotooltip_bigPromoter: has multiple closely related but subtly different meanings depending on context:

* In bacteria, a promoter is a cis-acting DNA sequence near the transcription start site of a gene or operon that binds to bacterial RNA polymerase. * In eukaryotes, the formal definition of a promoter (also called a basal promoter) is a RNA or other cis-acting regulatory elementsplugin-autotooltip__default plugin-autotooltip_bigCis-acting regulatory element: a DNA sequence that is usually located near and controls the expression of a gene or genes. Includes elements such as enhancers (e.g., $UAS_{GAL}$), repressors (e.g., $URS_{GAL}$), operators (e.g., $lacO$), promoters (e.g., the $GAL4$ promoter that contains the TATA box; another example is $lacP$ in E. coli), etc..
