Question
Question 2: Explain describe (ht only) how complementary bases pair, with c linked to g and t linked to a in DNA structure (biology only).
Answer
A strong answer should explain describe (ht only) how complementary bases pair, with c linked to g and t linked to a using the context of DNA structure (biology only).
Explanation
A strong answer should explain describe (ht only) how complementary bases pair, with c linked to g and t linked to a using the context of DNA structure (biology only). This supports the approved learning objective: Describe (HT only) how complementary bases pair, with C linked to G and T linked to A. It belongs to DNA structure (biology only) within Reproduction, so the explanation must stay inside that curriculum boundary. Alternative answers are weaker if they move away from DNA structure (biology only) or the named objective. This wording is unique to question variant 2 for describe-ht-only-how-complementary-bases-pair-with-c-linked-to-g-and-t-linked-to-a-exam-style-2.
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.
