DNA serves as the molecular basis for which processes?

• A. Inheritance and Evolution
• B. Energy Storage
• C. Membrane Formation
• D. Metabolic Catalysis

Answer: (A)

DNA's primary role is to store genetic information in the sequence of its bases and to pass that information from one generation to the next. This informational blueprint enables inheritance: organisms replicate their DNA and transmit it to offspring, ensuring traits are inherited. Variations arise from mutations in DNA, and natural selection acting on these variations over generations drives evolution. Other options miss the mark because energy storage is handled by special molecules like ATP, not DNA; membranes are built from lipids and proteins rather than nucleic acids; and while DNA governs which enzymes are produced, the actual catalysis of metabolic reactions is performed by enzymes themselves, not by DNA acting as a catalyst.
