Verified step by step guidance

Understand the question: The problem is asking about the class of biomolecules to which DNA and RNA belong. The options provided are carbohydrates, nucleic acids, lipids, and proteins.

Recall the structure and function of DNA and RNA: DNA (Deoxyribonucleic Acid) and RNA (Ribonucleic Acid) are molecules responsible for storing and transmitting genetic information in cells.

Identify the biomolecule class: DNA and RNA are composed of nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base. This structure is characteristic of nucleic acids.

Eliminate incorrect options: Carbohydrates are primarily energy sources and structural components, lipids are involved in energy storage and membrane structure, and proteins are functional molecules like enzymes and structural components. None of these match the role or structure of DNA and RNA.

Conclude: Based on their nucleotide composition and role in genetic information, DNA and RNA belong to the class of biomolecules known as nucleic acids.
