An example of prokaryotic gene expression is the lac operon. when a person is
they do not produce the enzyme which aids in the digestion of lactose, the sugar found in instead, lactose travels farther down the digestive tract into the large intestine, where the genes in the bacteria, , are turned on to create the / needed to digest the lactose. in e. coli, when lactose is present, it acts as an inducer and binds to the protein, keeping it from attaching to the then is able to attach to the gene and the gene by matching up the when lactose is not present, the protein binds to the 13 and transcription is blocked. this is an example of gene expression (production of proteins) being controlled at question 40 options:
