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 explain that a sequence of three bases codes for a particular amino acid.
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 explain that a sequence of three bases codes for a particular amino acid.
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 explain that a sequence of three bases codes for a particular amino acid.. 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 explain that a sequence of three bases codes for a particular amino acid. is correct because A DNA base sequence is the storage format; a gene is the named instruction unit. The learning objective says students must explain that a sequence of three bases codes for a particular amino acid, 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

Misunderstanding Base Sequences

Students often confuse the concept of a sequence of three bases coding for an amino acid with the idea that each base individually codes for an amino acid.

Emphasize that it is the triplet of bases that codes for a specific amino acid, not each base on its own.
