WebEach cis- regulatory region requires a unique mix of molecules in order to bind to the promoter and begin transcription of the gene. The embryo has four bands that express the gene. Each band has a different mix of activator molecules and is activated by a different cis-regulatory region. WebCis-regulatory regions bind DNA transcriptase to the gene. Transcription occurs when a cis-regulatory region binds to a promoter. Genes only have a single cis-regulatory region. Cis-regulatory regions control gene transcription. Each cis-regulatory region interacts with a unique mix of This problem has been solved! WebA key control point in regulating expression is the initiation of transcription, and much is known about how the transcription machinery assembles near the site of initiation and starts transcribing ( Luse, 2014; Robinson et al., 2016 ). ordering crabs online
