Verified step by step guidance

Step 1: Begin by understanding the classification of biomolecules. Biomolecules are broadly categorized into four main types: carbohydrates, lipids, proteins, and nucleic acids.

Step 2: Recall the structural and functional characteristics of nucleic acids. DNA (Deoxyribonucleic acid) and RNA (Ribonucleic acid) are polymers made up of nucleotide monomers, which consist of a sugar, phosphate group, and nitrogenous base.

Step 3: Compare the given options. Carbohydrates are energy-providing molecules, lipids are hydrophobic molecules involved in energy storage and membrane structure, and proteins are composed of amino acids and perform diverse functions like catalysis and structural support. Nucleic acids, on the other hand, store and transmit genetic information.

Step 4: Identify that DNA and RNA are nucleic acids because their primary role is in genetic information storage and transfer, which aligns with the definition of nucleic acids.

Step 5: Conclude that the correct classification for DNA and RNA is 'Nucleic acids,' based on their structure and function.
