Which organism would most likely have a proteome that is much larger than the genome?
A) One with a great deal of highly repetitive DNA
B) One with little highly repetitive DNA
C) One with a great deal of alternative splicing
D) One with little alternative splicing
E) One with a lot of secondary metabolites

Question

Quizplus · Accepted Answer

Alternative splicing allows for the generation of multiple protein isoforms from a single gene, resulting in a larger proteome than genome. Highly repetitive DNA does not necessarily correspond to an enlarged proteome, as repetitive regions are typically not transcribed or translated. The presence of secondary metabolites is also not directly related to proteome size.
