The correct Answer is:
**Step-by-Step Solution:** 1. **Definition of DNA**: DNA stands for Deoxyribonucleic Acid. It is the hereditary material in all known living organisms and many viruses. 2. **Structure of DNA**: DNA has a double helical structure, which means it consists of two strands that wind around each other. This double-stranded nature is crucial for its function in storing genetic information. 3. **Components of DNA**: Each strand of DNA is made up of smaller units called nucleotides. A nucleotide consists of three components: - A phosphate group - A pentose sugar (deoxyribose in the case of DNA) - A nitrogenous base (which can be adenine (A), thymine (T), guanine (G), or cytosine (C)) 4. **Base Pairing**: The nitrogenous bases pair specifically: adenine pairs with thymine (A-T) and guanine pairs with cytosine (G-C). These pairs are held together by hydrogen bonds. 5. **Function of DNA**: DNA serves as the blueprint for all living organisms, carrying the genetic instructions used in growth, development, functioning, and reproduction. 6. **Conclusion**: Therefore, the correct answer to the question "DNA is" is that DNA is deoxyribonucleic acid. ---
