The proteome is all the proteins produced by an organism. The genome is the totality of all genes of an organism. If the proteome is much larger than the genome, which of the following statements would be accurate?

A) The number of monomeric subunits found in proteins is fewer than the number of monomeric subunits found in genes.
B) Noncoding DNA is important in determining the proteome.
C) This finding lends support to the one gene-one enzyme hypothesis.
D) At least in some cases, a single gene must code for more than one protein.
