The Lac Operon and lactose intolerance?

[Em.]

What is the link between the two? Is lactose intolerance a result of something not functioning properly in the lac operon?

[Jenny_2108]

Lac Operon is a single expressible unit of DNA to produce messenger RNA in the process of protein transcription, encodes for lactose metabolism in the bacterium Escherichia coli

Human genes are not organised in operons in the same way as bacteria do. Lac Operon is gene regulation at A-level in bacteria, which is simpler than human gene regulation

Human has different genes to produce enzyme for lactose metabolism (lactose tolerance) unless they are said to be intolerant. This is due to evolution

I think its in unit 4 change over time but I havent studied at school yet so I'm not totally sure about it. Maybe someone in AN can help you better than me
