the benefit of the bacterial operon is that

points
multiple choice
the structural genes can be regulated individually, affording the cell more control over the protein products
the split genes can be cut and spliced back together with greater precision than with single genes
since the proteins coded for by the operon structural genes work as a team, they are regulated (i.e. induced or repressed) as a team, thus saving energy
they are much less prone to mutation than individual genes

Explanation:

In bacteria, an operon is a cluster of genes with related functions. The proteins coded by the structural genes in an operon often work together (e.g., in a metabolic pathway). Regulating them as a group (either all induced or all repressed) is more energy - efficient than regulating each gene separately. For example, in the lac operon, the genes for lactose metabolism are regulated together. When lactose is present, all the genes needed for its breakdown (such as lacZ, lacY, and lacA) are induced simultaneously.

Answer:

since the proteins coded for by the operon structural genes work as a team, they are regulated (i.e. induced or repressed) as a team, thus saving energy
