State
A prokaryotic operon groups several genes under one promoter and one operator, so a single regulatory event switches all the genes together.
Show
An operon's operator sequence sits between its promoter and structural genes, controlling whether RNA polymerase can transcribe them.
Watch for
An operon's genes are all transcribed together as one unit — they are not each controlled by a separate promoter.
