For example (1) a transcribed and translated transcription factor protein derived from the trans-regulatory element; and a (2) DNA regulatory element that is adjacent to the regulated gene. This is in contrast to cis-regulatory elements that work through an intramolecular interaction between different parts of the same molecule: (1) a ge… WebThere are cis-regulatory and trans-regulatory elements. Cis-regulatory elements are often binding sites for one or more trans-acting factors.
