The single stranded but complementary ends of the two DNA molecules are called "sticky ends" because:
Correct answer: B. They can bind by complementary base pairing
- A. They cannot bind
- B. They can bind by complementary base pairing
- C. They can bind by non-complementary base pairing
- D. They cannot bind due to noncomplementary base pairing
Explanation
Due to base pairing affinity sticky ends can stick together, whenever brought closer to each other.
