Scientists have developed a nucleic acid (HNA) whose sugar contains the same number of carbon atoms as glucose rather than deoxyribose. Even though HNA can store genetic information, naturally occurring DNA polymerase is unable to replicate HNA. Which statements might account for the fact that naturally occurring DNA polymerase cannot replicate HNA?
- A1, 2, 3 and 4
- B1 and 4 only
- C2 and 3 only
- D3 and 4 only
