What is the main function of nucleic acids?

Holding genetic information
Regulating what enters and leaves the cell
Providing energy for metabolic reactions
Modifying proteins

The correct answer is: Holding genetic information

Nucleic acids are large molecules that make up genetic material and are essential for the storage and transmission of genetic information. They act as templates for protein synthesis and carry instructions for the development and functioning of all living organisms. Option B is incorrect because membrane proteins are responsible for regulating what enters and leaves the cell. Option C is incorrect because nucleic acids do not provide energy for metabolic reactions, that is the role of carbohydrates and lipids. Option D is incorrect because proteins are modified by other molecules such as enzymes, not nucleic acids.
