answer. A corepressor is, by definition, In the field of molecular biology, "a substance that inhibits the expression of genes. In prokaryotes, corepressors are small molecules whereas in eukaryotes, corepressors are proteins." In the case of E. coli, the corepressor is the Tryptophan. question.The process of turning on a gene to produce RNA and protein is called gene expression. Whether in a simple unicellular organism or a complex multi-cellular organism, each cell controls when and how its genes are expressed. The expression of a gene is a highly regulated process.3.8 The control of gene expression (A-level only) Cells are able to control their metabolic activities by regulating the transcription and translation of their genome.
