The genes lacZ, lacY and lacA are transcribed from a single promoter (P) that produces a single mRNA from which the three proteins are translated. The operon is regulated by Lac repressor, the product ...

Required for the transport and metabolism of lactose in Escherichia Coli (E. coli).The lactose operon or lac operon consists of three structural genes namely lacZ, lacY, and lacA that encode proteins ...

Last week I finally addressed promoters and gave a bit of background on the lac operon. Looking back, I feel that I didn't give the topic of operons adequate treatment. They are a very crucial aspect ...
