Question
- A. Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. This matches DNA and the genome because students must explain that each gene codes for a sequence of amino acids to make a specific protein.
- 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 and the genome.
- C. Partial misconception: Treating DNA as if it always means one gene. This misses the objective focus on explain that each gene codes for a sequence of amino acids to make a specific protein.
- D. Terminology mix-up: It moves into a neighbouring Unit 4.6 idea rather than Reproduction / DNA and the genome.
Answer
The correct option is Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. This matches DNA and the genome because students must explain that each gene codes for a sequence of amino acids to make a specific protein.. It is the only option that keeps DNA vs genes separate and answers the approved learning objective in DNA and the genome.
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 and the genome because students must explain that each gene codes for a sequence of amino acids to make a specific protein.. Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. This matches DNA and the genome because students must explain that each gene codes for a sequence of amino acids to make a specific protein. 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 each gene codes for a sequence of amino acids to make a specific protein, so the answer must stay inside DNA and the genome. 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
Gene‑Protein Link Misconception
Students often think a gene is a single amino acid or that the gene’s DNA sequence directly becomes the protein sequence without any intermediate steps.
Explain that a gene is a DNA segment that is first transcribed into mRNA, which is then translated by ribosomes into a polypeptide chain; the codon sequence in the mRNA determines the order of amino acids in the final protein.
