Which of the following is NOT a component of the lac operon?
Step 1: Understand what the lac operon is. It is a group of genes in bacteria that help them digest lactose.
Step 2: Identify the components of the lac operon. These include the promoter, operator, and structural genes.
Step 3: Recognize that an enhancer is not part of the lac operon. Enhancers are found in eukaryotic genes, not in prokaryotic operons like the lac operon.
Step 4: Conclude that the correct answer to the question is that an enhancer is NOT a component of the lac operon.
