Cis-acting elements examples

WebMay 1, 2024 · Answers and Replies. Basically, cis is an element that is on the same DNA molecules and trans is something on a different molecules. Best example is with the lac operon. In wild type strain, LacI and lacO are cis acting elements. If you knock-out lacI and complement the defective strain with a plasmid carrying lacI.
