Transactivator: Using more formal genetic verbiage, a gene productplugin-autotooltip__default plugin-autotooltip_bigGene product: the molecule that is produced based on information contained within a gene and provides function to the organism. 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 (usually a proteinplugin-autotooltip__default plugin-autotooltip_bigProtein: a molecule that is formed by the translation of messenger RNAs (mRNAs). Functions that proteins provide are what usually give organisms their phenotypes.) for which its geneplugin-autotooltip__default plugin-autotooltip_bigGene: read Chapters 02, 03, 04, 05, and 06 for a definition of gene :-) acts in transplugin-autotooltip__default plugin-autotooltip_bigCis and trans: In genetics, cis and trans are terms used to describe the relative physical locations of genes or genetic elements. If two genes are in cis, this means that they are physically located on the same DNA molecule. If two genes are in trans, this means that they are physically located on two different to activate the expressionplugin-autotooltip__default plugin-autotooltip_bigExpression: a term used to describe the idea that the function of a gene is apparent and can be observed.

* 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 sequencesplugin-autotooltip__default plugin-autotooltip_bigSequence: the precise order of monomers in a polymer. In DNA, it refers to the order of G, A, T, and C nucleotides. In RNA, it refers to the order of G, A, U, and C nucleotides. In proteins, it refers to the order of amino acids. to activate the 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).
