Reproduction

Question

A. Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. This matches DNA structure (biology only) because students must recall that DNA contains the four bases A, C, G and T.
B. Common misconception: Explaining protein coding without naming the gene as the relevant section of DNA. This would blur DNA vs genes instead of testing DNA structure (biology only).
C. Partial misconception: Treating DNA as if it always means one gene. This misses the objective focus on recall that DNA contains the four bases A, C, G and T.
D. Terminology mix-up: It moves into a neighbouring Unit 4.6 idea rather than Reproduction / DNA structure (biology only).

Answer

Explanation

The correct option is Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. This matches DNA structure (biology only) because students must recall that DNA contains the four bases A, C, G and T.. Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. This matches DNA structure (biology only) because students must recall that DNA contains the four bases A, C, G and T. is correct because A DNA base sequence is the storage format; a gene is the named instruction unit. The learning objective says students must recall that DNA contains the four bases A, C, G and T, so the answer must stay inside DNA structure (biology only). The alternative options are wrong because they either explaining protein coding without naming the gene as the relevant section of dna., treating dna as if it always means one gene., or drift away from do not use dna, gene, and chromosome as interchangeable answers..

Common mistake

Misidentifying DNA Bases

Students often confuse the four bases of DNA, mixing up their letters or omitting one or more of them.

To fix this, students should create a mnemonic or visual aid to remember the bases A (adenine), C (cytosine), G (guanine), and T (thymine) and practice recalling them regularly.
