It may be considered the opposite of cis-acting (cis-regulatory, cis-regulation), which, in general, means "acting from the same molecule" (i.e., intramolecular). In the context of transcription regulation, a trans-acting factor is usually a regulatory protein that bi…

Webcis /I> configuration describes two sites on the same molecule of DNA. trans /I> configuration of two sites refers to their presence on two different molecules of DNA (chromosomes).
