Next comes translating instructions in that mRNA to make proteins. For that to happen, the mRNA must journey out of the nucleus and into the cytoplasm where the protein-making factories reside. WebGenes in an operon are transcribed as a group and have a single promoter. Each operon contains regulatory DNA sequences, which act as binding sites for regulatory proteins that promote or inhibit transcription. Regulatory proteins often bind to small molecules, which can make the protein active or inactive by changing its ability to bind DNA. ct permit for home repairs
