Question

which macromolecule is primarily responsible for storing genetic information? carbohydrates lipids proteins nucleic acids

Explanation:

To determine the macromolecule responsible for storing genetic information, we analyze each option:

• Carbohydrates: Mainly provide energy (e.g., glucose, starch). Not for genetic info.
• Lipids: Store energy (e.g., fats) and form cell membranes. Not for genetic info.
• Proteins: Perform structural/functional roles (e.g., enzymes, antibodies). Not for genetic info.
• Nucleic Acids: Include DNA and RNA. DNA stores genetic info; RNA helps express it.

Answer:

D. Nucleic Acids (assuming the options are labeled A - D as Carbohydrates, Lipids, Proteins, Nucleic Acids respectively)
