Which of the Following Accurately Describes the Structure of Fibrous

Which of the following accurately describes the structure of fibrous proteins?

A) Fibrous proteins usually contain a number of different domains with different structural motifs.
B) Fibrous proteins are composed of an equal mixture of α helices and β sheets with interconnecting looped segments.
C) Fibrous proteins have an extensive tertiary and quaternary structure that affects the strength and elasticity of each fiber.
D) Fibrous proteins have a simple primary structure and very little secondary structure,resulting in long,thin fibers.
E) Fibrous proteins are usually composed of either α helices or β sheets throughout the molecule,giving them a highly ordered,repetitive structure.
