The correct Answer is:
**Step-by-Step Solution:** 1. **Identify the Sugar in DNA:** - DNA (Deoxyribonucleic Acid) contains a specific type of sugar. The sugar present in DNA is called deoxyribose. 2. **Understand the Structure of Deoxyribose:** - Deoxyribose is a five-carbon sugar (pentose). Its structure includes five carbon atoms, and it is a cyclic molecule. 3. **Differentiate Deoxyribose from Other Sugars:** - Unlike ribose, which is found in RNA (Ribonucleic Acid), deoxyribose lacks one hydroxyl group (-OH) at the second carbon position. This absence is what gives deoxyribose its name, as "deoxy" indicates the removal of an oxygen atom. 4. **Relate the Sugar to the Function of DNA:** - The sugar in DNA, deoxyribose, is crucial for the formation of the DNA backbone, which consists of alternating sugar and phosphate groups. This structure is essential for the stability and function of DNA. 5. **Conclusion:** - Therefore, the sugar present in DNA is deoxyribose, which is integral to the structure and function of DNA. ---
