Question
- A. It means students should be able to describe the long DNA strands as alternating sugar and phosphate sections with bases attached to the sugars.
- 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 the long DNA strands as alternating sugar and phosphate sections with bases attached to the sugars..
Explanation
The correct option is It means students should be able to describe the long DNA strands as alternating sugar and phosphate sections with bases attached to the sugars. because it directly reflects the approved learning objective: Describe the long DNA strands as alternating sugar and phosphate sections with bases attached to the sugars..
Common mistake
Misidentifying the backbone
Students often say the DNA backbone is made of bases and sugars, confusing the sugar‑phosphate backbone with the base pairs.
Explain that the backbone is a repeating sugar‑phosphate chain; the bases (A, C, G, T) attach to the sugars and face inward to pair with complementary bases on the opposite strand.
