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.

WebIt seems more plausible that GreA autoregulation (GraL acting in cis) had evolved first, and GraL acting in trans arose as a secondary function. It should be noted that regulation by early transcriptional termination at the 5′UTR is a common mechanism among bacteria, where attenuators, riboswitches, or T-boxes are employed [ 36 ].
