• A. Providing structural support to cells
• B. Catalyzing metabolic reactions
• C. Transporting oxygen in the blood
• D. Storing and transmitting genetic information

Answer: (D)

Verified step by step guidance

1. Understand the role of nucleic acids: Nucleic acids, such as DNA and RNA, are essential biomolecules that store and transmit genetic information within a cell. They are not involved in providing structural support, catalyzing reactions, or transporting oxygen.
2. Identify the components of nucleic acids: Nucleic acids are composed of nucleotides, which are the building blocks. Each nucleotide consists of a sugar, a phosphate group, and a nitrogenous base.
3. Recognize the function of nucleotides: Nucleotides are involved in storing genetic information in sequences of bases (adenine, thymine, cytosine, guanine in DNA; adenine, uracil, cytosine, guanine in RNA) and transmitting this information during processes like replication and transcription.
4. Differentiate nucleic acids from other biomolecules: Proteins, not nucleic acids, are typically responsible for catalyzing metabolic reactions (as enzymes) and transporting oxygen (as hemoglobin). Structural support is often provided by proteins and carbohydrates.
5. Conclude the primary function: The primary function of nucleic acids and nucleotides is to store and transmit genetic information, which is crucial for inheritance and the functioning of living organisms.
