What is a Reason That the Proteome is Larger Than

Question

What is a reason that the proteome is larger than the genome?
A) Alternative splicing
B) Proteins are constantly being synthesized and degraded.
C) Each protein has a specific function which are quite varied while the genes in the genome are only transcribed
D) Each protein has multiple functional domains while each gene consists of three basic parts.

Accepted Answer

Alternative splicing allows a single gene to produce multiple proteins, thereby increasing the diversity of the proteome beyond the number of genes in the genome.
