Many aspects of gene function can be nicely explained with the one-
gene-one-enzyme hypothesis, which states that a gene controls the
production of an enzyme. Which of the following findings about
gene expression, though, requires an expansion of this simple
concept?
Non-enzyme proteins are made from genes too.
Some genes code for RNA molecules only.
Enzymes composed of different polypeptides are coded for by more
than one gene.
