Logic: It refers to the carbon atom of the deoxyribose sugar. The 5' end has a free phosphate group, and the 3' end has a free hydroxyl (-OH) group. Conclusion

Remember, the helix is not just a pretty shape; it is the architecture of heredity. Use these answers as a guide, but focus on the conceptual reasoning. When you can explain why the lagging strand needs Okazaki fragments, you are ready for the AP exam. Logic: It refers to the carbon atom of the deoxyribose sugar
