Question
Question 1: Explain explain (ht only) how dna structure affects the protein made by controlling the amino acid sequence in DNA structure (biology only).
Answer
A strong answer should explain explain (ht only) how dna structure affects the protein made by controlling the amino acid sequence using the context of DNA structure (biology only).
Explanation
A strong answer should explain explain (ht only) how dna structure affects the protein made by controlling the amino acid sequence using the context of DNA structure (biology only). This supports the approved learning objective: Explain (HT only) how DNA structure affects the protein made by controlling the amino acid sequence. 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 1 for explain-ht-only-how-dna-structure-affects-the-protein-made-by-controlling-the-amino-acid-sequence-exam-style-1.
Common mistake
Misunderstanding Base Pairing Rules
Students often think that any base can pair with any other base, or that the order of bases in DNA directly determines the amino acid sequence without considering codon structure.
Explain that only complementary bases pair (A with T, C with G) and that the DNA sequence is read in triplets (codons) on the mRNA, each codon specifying a particular amino acid. Emphasise that the sequence of codons, not the individual bases alone, determines the protein sequence.
