Something To Bind With....

a: Gene promoter ~
b: a doorknob

What: "Here's an analogy. A promoter is like a doorknob, in that the promoters of many operons are similar. An operator is like the keyhole in a doorknob, in that each door is locked by only a specific key, which in this analogy is a specific regulatory protein."
