Repressor: a DNAplugin-autotooltip__default plugin-autotooltip_bigDNA: deoxyribonucleic acid. The genetic material for nearly all life on Earth. binding 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. that binds to negatively acting cisplugin-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-acting elements such as operatorsplugin-autotooltip__default plugin-autotooltip_bigOperator: in bacterial genetics, an operator is a cis-acting genetic element that negatively regulates the expression of nearby genes. $lacO$ of the Lac operon is an example of an operator. in bacteriaplugin-autotooltip__default plugin-autotooltip_bigBacteria: Single-celled organisms that also utilize DNA and the standard genetic code as all organisms on earth, but unlike eukaryotes do not have intracellular membranes and membrane-bound organelles. In this book we use bacteria and prokaryote interchangeably. to inhibit 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.. Compare to negative regulatorplugin-autotooltip__default plugin-autotooltip_bigNegative regulator: in the context of gene regulation, a negative regulator is a gene whose activity blocks the expression of another gene. Compare to repressor..
