The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks about the charge of DNA. 2. **Identifying the Charge**: DNA is known to be a negatively charged molecule. 3. **Reason for the Charge**: The negative charge of DNA arises from the presence of negatively charged oxygen atoms. 4. **Source of the Negative Charge**: The negatively charged oxygen atoms are part of the phosphate groups that make up the backbone of the DNA molecule. 5. **Conclusion**: Therefore, DNA is negatively charged due to the phosphate groups in its structure. **Final Answer**: DNA is negatively charged. ---
