DNA is best described as?

• A. A carbohydrate used for energy.
• B. A protein that forms hair.
• C. A lipid used for energy storage.
• D. A molecule that contains genetic information.

Answer: (D)

DNA is best described as a molecule that contains genetic information. It stores the instructions needed to build and regulate an organism, encoded in the sequence of its nucleotide bases. This information is passed from cell to cell and from one generation to the next as DNA replicates, ensuring heredity. Unlike carbohydrates, proteins, or lipids, which have roles in energy, structure, and storage, DNA’s primary function is to carry the genetic code that guides development and cellular function. The information in DNA is read and used through transcription and translation, linking the genetic sequence to the production of proteins that carry out most cellular tasks.
