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 … WebFeb 7, 2024 · Since very few canonical cis-acting elements (5′ splice site (5′ss), 3′ss, and BPS) are affected by editing 27, we believe that ADAR proteins may regulate splicing …
