| Front | Describe and explain how the structure of DNA results in accurate replication. (4 marks) |
|---|---|
| Back | two strands therefore semi-conservative replication (possible); base pairing/hydrogen bonds holds strands together hydrogen bonds weak/easily broken, allow strands to separate; bases (sequence) (exposed so) act as template /can be copied; A with T, C with G / complementary copy; DNA one parent and one new strand; |
