Trans-regulatory elements work through an intermolecular interaction between two different molecules and so are said to be "acting in trans". For example (1) a transcribed and translated transcription factor protein derived from the trans-regulatory element; and a (2) DNA regulatory element that … Zobacz więcej Trans-regulatory elements (TRE) are DNA sequences encoding upstream regulators (ie. trans-acting factors), which may modify or regulate the expression of distant genes. Trans-acting factors interact with cis-regulatory elements Zobacz więcej Trans-acting factors can be categorized by their interactions with the regulated genes, cis-acting elements of the genes, or the gene products. DNA binding DNA binding trans-acting factors regulate gene … Zobacz więcej • Cis-regulatory element Zobacz więcej WitrynaA strain of bacteria containing F' factor genes is called a. cis acting element. The lac operator site within the lac operon is an example of a. camp. The ability of glucose to repress the lac operon depends on which effector molecules? tryptophan.
