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 ...

Can the presence of glucose itself activate the genes that will break it down? It does in bacteria through a process known as positive transcription control.

The lac operon genes are expressed to digest the available lactose until this sugar is depleted, at which point the operon shuts down. However, the lac operon was far from solved. “ [It] turned out ...

The genes and important sequences for the regulation of the lac operon are organized such that several mediators can fine tune expression of the three genes in the operon itself— lacZ, lacY, and lacA.

New research suggests a possible explanation for the organization of operons, jointly controlled clusters of genes that evolved in bacterial chromosomes. Operons, which are found in the chromosomes of ...

Eurofins Scientific, the global leader in bio-analytical testing, and one of the world leaders in genomic services, announces that it is combining its competencies to provide the most complete suite ...
