An example of a cis-acting regulatory sequence is the operator in the lac operon. This DNA sequence is bound by the lac repressor, which, in turn, prevents transcription of the adjacent genes on the same DNA molecule. The lac operator is, thus, considered to "act in cis" on the regulation of the nearby genes. The operator itself does not code for any protein or RNA. In contrast, trans-regulatory elements are diffusible factors, usually proteins, that may modify the … 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 to regulate gene expression. TRE mediates expression profiles of a large number of … See more 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 … See more Trans-acting factors can be categorized by their interactions with the regulated genes, cis-acting elements of the genes, or the gene products.
