Question
- A. It means students should be able to describe (HT only) how complementary bases pair, with C linked to G and T linked to A.
- B. It means A is never assessed in Reproduction.
- C. It means learners only need to memorise the topic title for DNA structure (biology only).
- D. It means students should give the opposite of the approved learning objective.
Answer
The correct answer is It means students should be able to describe (HT only) how complementary bases pair, with C linked to G and T linked to A..
Explanation
The correct option is It means students should be able to describe (HT only) how complementary bases pair, with C linked to G and T linked to A. because it directly reflects the approved learning objective: Describe (HT only) how complementary bases pair, with C linked to G and T linked to A..
Common mistake
Misidentifying base‑pairing rules
Students often state that A pairs with C and G pairs with T, confusing the complementary base‑pairing scheme.
Remind them that adenine (A) always pairs with thymine (T) and cytosine (C) always pairs with guanine (G); the A–T and C–G pairs are the only correct complementary pairings in DNA.
