Cis vs trans biology
Webcis- and trans - Regulatory Elements The lac operon includes DNA sequences that do not encode proteins, but are instead binding sites for proteins that regulate transcription of the operon. In the lac operon, these sequences are called P (promoter), O (operator), and CBS (CAP-binding site). WebCis-regulatory elements are often binding sites for one or more trans-acting factors. To summarize, cis-regulatory elements are present on the same molecule of DNA as the …
