  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

    Cis-regulatory DNA sequences that are located in DNA regions distant from the promoters of genes can have very large effects on gene expression, with some genes undergoing up to 100-fold increased expression due to such a cis-regulatory sequence. [3] These cis-regulatory sequences include enhancers, silencers, insulators and tethering elements. [4]

  4. 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.

  5. Regulation of gene expression - Wikipedia

    en.wikipedia.org/wiki/Regulation_of_gene_expression

    Gene regulation works using operators and repressors in bacteria. Gene Regulation can be summarized by the response of the respective system: Inducible systems - An inducible system is off unless there is the presence of some molecule (called an inducer) that allows for gene expression. The molecule is said to "induce expression".

  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. Cis-regulatory element - Wikipedia

    en.wikipedia.org/wiki/Cis-regulatory_element

    Cis-regulatory elements (CREs) or cis-regulatory modules (CRMs) are regions of non-coding DNA which regulate the transcription of neighboring genes.CREs are vital components of genetic regulatory networks, which in turn control morphogenesis, the development of anatomy, and other aspects of embryonic development, studied in evolutionary developmental biology.

  8. Coding region - Wikipedia

    en.wikipedia.org/wiki/Coding_region

    The coding region of a gene, also known as the coding DNA sequence (CDS), is the portion of a gene's DNA or RNA that codes for a protein. [1] Studying the length, composition, regulation, splicing, structures, and functions of coding regions compared to non-coding regions over different species and time periods can provide a significant amount of important information regarding gene ...

  9. Master regulator gene - Wikipedia

    en.wikipedia.org/wiki/Master_regulator_gene

    In genetics, a master regulator gene is a regulator gene at the top of a gene regulation hierarchy, particularly in regulatory pathways related to cell fate and differentiation. Examples [ edit ]
