How do nucleic acids differ from proteins in their biological roles?

• Nucleic acids store energy, while proteins store genetic information.

• Nucleic acids catalyze reactions, while proteins provide structural support.

• Nucleic acids store and transmit genetic information, while proteins perform a variety of functions including catalysis and support.

• Nucleic acids form cell membranes, while proteins are involved in energy storage.
