A type of gene expression control in bacteria. Transcription of a gene under this type of control is induced only when a repressor protein present in the cell is inactivated.
Gene expression is the process by which the genetic code-the nucleotide sequence-of a gene is used to direct protein synthesis and produce the structures of the cell. Genes that code for amino acid sequences are known as 'structural genes'. The process of gene expression involves two main stages:echanisms of gene regulation include: 1  Regulating the rate of transcription. 2  Regulating the processing of RNA molecules, including alternative splicing to produce more than one protein product from a single gene. 3  Regulating the stability of mRNA molecules. 4  Regulating the rate of translation.
