  2. Regulator gene - Wikipedia

    en.wikipedia.org/wiki/Regulator_gene

    Gene regulatory pathway. In genetics, a regulator gene, regulator, or regulatory gene is a gene involved in controlling the expression of one or more other genes. Regulatory sequences, which encode regulatory genes, are often at the five prime end (5') to the start site of transcription of the gene they regulate. In addition, these sequences ...

  3. Regulatory sequence - Wikipedia

    en.wikipedia.org/wiki/Regulatory_sequence

    An active enhancer regulatory sequence of DNA is enabled to interact with the promoter DNA regulatory sequence of its target gene by formation of a chromosome loop. This can initiate messenger RNA (mRNA) synthesis by RNA polymerase II (RNAP II) bound to the promoter at the transcription start site of the gene. The loop is stabilized by one ...

  4. Regulation of gene expression - Wikipedia

    en.wikipedia.org/wiki/Regulation_of_gene_expression

    Regulation of gene expression, or gene regulation, [1] includes a wide range of mechanisms that are used by cells to increase or decrease the production of specific gene products (protein or RNA). Sophisticated programs of gene expression are widely observed in biology, for example to trigger developmental pathways, respond to environmental ...

  5. Gene regulatory network - Wikipedia

    en.wikipedia.org/wiki/Gene_regulatory_network

    Structure of a gene regulatory network Control process of a gene regulatory network. A gene (or genetic) regulatory network (GRN) is a collection of molecular regulators that interact with each other and with other substances in the cell to govern the gene expression levels of mRNA and proteins which, in turn, determine the function of the cell.

  6. Transcriptional regulation - Wikipedia

    en.wikipedia.org/wiki/Transcriptional_regulation

    An active enhancer regulatory sequence of DNA is enabled to interact with the promoter DNA regulatory sequence of its target gene by formation of a chromosome loop. This can initiate messenger RNA (mRNA) synthesis by RNA polymerase II (RNAP II) bound to the promoter at the transcription start site of the gene. The loop is stabilized by one ...

  7. Biological process - Wikipedia

    en.wikipedia.org/wiki/Biological_process

    Regulation of biological processes occurs when any process is modulated in its frequency, rate or extent. Biological processes are regulated by many means; examples include the control of gene expression, protein modification or interaction with a protein or substrate molecule.

  8. Cis-regulatory element - Wikipedia

    en.wikipedia.org/wiki/Cis-regulatory_element

    One cis-regulatory element can regulate several genes, [2] and conversely, one gene can have several cis-regulatory modules. [3] Cis-regulatory modules carry out their function by integrating the active transcription factors and the associated co-factors at a specific time and place in the cell where this information is read and an output is ...

    cadastral gene A regulatory gene that restricts the expression of other genes to specific tissues or body parts in an organism, typically by producing gene products which variably inhibit or permit transcription of the other genes in different cell types. [4] The term is used most commonly in plant genetics. cadherin
