What is the primary function of nucleic acids?

• A. To provide energy
• B. To store genetic information
• C. To build cell structures
• D. To catalyze reactions

Answer: (B)

Nucleic acids, which include DNA and RNA, play a crucial role in the storage and transmission of genetic information within living organisms. Their primary function is to encode the instructions needed for the development, functioning, growth, and reproduction of all forms of life. DNA contains the genetic blueprint that is passed from one generation to another, ensuring that the necessary information for producing proteins and other vital molecules is preserved and transmitted. RNA, on the other hand, is involved in translating that genetic information into proteins, which perform various functions within cells. While options like providing energy, building cell structures, and catalyzing reactions involve other crucial biomolecules, such as carbohydrates, proteins, and enzymes, these roles are not the primary function associated with nucleic acids. Nucleic acids are fundamentally about the information they carry, making the storage of genetic information their main role.
