The lac operon is a set of genes which are responsible for the metabolism of lactose in some bacterial cells. Students will explore the effects of mutation within the lac operon by adding or removing genes from the DNA.
Predicts the effects on lactose metabolism when the various genes and DNA control elements are mutated (added or removed).
Predicts the effects on lactose metabolism when the concentration of lactose is changed.
Explain the roles of Lacl, LacZ, and LacY in lactose regulation.
