Weba DNA- or RNA-binding protein that inhibits the expression of one or more genes by binding to the operator or associated silencers. CpG. A short stretch of DNA where there are regions with a high concentration of CpG dinucleotides. P indicates a connection via a phosphodiester bond. Insulator. sequences located between an enhancer and a promoter. 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 … See more Cis-regulatory elements (CREs) or Cis-regulatory modules (CRMs) are regions of non-coding DNA which regulate the transcription of neighboring genes.
