Scientists have produced a nucleic acid, HNA, whose sugar has the same number of carbon atoms as glucose rather than deoxyribose. Even though HNA can store genetic information, naturally occurring DNA polymerase cannot copy HNA. Which statements could account for naturally occurring DNA polymerase being unable to copy HNA?
- A1, 2, 3 and 4
- B1 and 4 only
- C2 and 3 only
- D3 and 4 only
