Question

which class of macromolecules store and communicate genetic information? carbohydrates lipids proteins nucleic acids this is a required question

Explanation:

To determine the class of macromolecules that store and communicate genetic information, we analyze each option:

• Carbohydrates: Mainly provide energy (e.g., glucose) or structural support (e.g., cellulose), not genetic info storage.
• Lipids: Function in energy storage (e.g., fats), cell membrane structure, and signaling, not genetic info.
• Proteins: Perform various functions like enzymes, structural support, and transport, but do not store genetic information.
• Nucleic acids: Include DNA (stores genetic information) and RNA (involved in communicating/expressing genetic information, e.g., during transcription and translation).

Answer:

D. nucleic acids
