"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 … " - Cis-acting vs trans-acting

Webcis versus trans-acting factors. Most often, signal elements act only on the intramolecular nucleotide sequence to which they are attached, and they are said to act "in cis". Intron removal in eukaryotes involves cis-splicing. Interaction with signal factors -- usually protein molecules -- turns signal elements on or off. WebFeb 21, 2024 · Cis-acting regulatory sequence elements are sequences contained in the 3′ and 5′ untranslated region, introns, or coding regions of precursor RNAs and mature mRNAs that are selectively recognized by a complementary set of one or more trans-acting factors to regulate posttranscriptional gene expression.

WebCis-acting and Trans-acting Elements: In cells with two copies of lac operons, it is important to consider what each lac operon can do to affect lactose metabolism. An operator is only able to block transcription on its own strand of DNA. The promoter can be recognized to start transcription, but it only starts transcription on that strand of DNA. Webcis-acting DNA elements The gene products encoded by trans-acting elements perform their function by associating with regulatory sequences distant from the gene from which they were transcribed Trans-acting proteins that influence transcription are commonly referred to as transcription factors.
