Gene Regulation Using the Lac Operon Abstract Gene regulation in cells has been studied extensively in both eukaryotic and prokaryotic organisms. Gene control is employed as a way of saving the cell energy by only producing those enzymes it needs. In eukaryotes, genes are regulated so as maintain levels of cell specificity. In this experiment, the restriction of the production of the â-galactosidase enzyme in the prokaryote Escherichia coli can be achieved by employing the …showed first 75 words of 1096 total…

Aside from minimal glitches, this experiment successfully demonstrated how the lac operon works to regulate the gene expression of the gene coding for the â-galactosidase enzyme. Sources 1.)
