Natural Proteins Most Commonly Contain Linear Polypeptides Between 100 and 1000

Multiple Choice

Natural proteins most commonly contain linear polypeptides between 100 and 1000 residues in length.One of the reasons polypeptides outside this range may be disfavored is that

A) larger polypeptides would likely be insoluble.
B) smaller polypeptides do not form stable folded structures.
C) smaller polypeptides typically assemble into prion-like aggregates.
D) amide linkages are not strong enough to keep larger polypeptides intact.
E) ribosomes are unable to synthesize larger polypeptides.
