Question
- A. CGEQ64: Use tumour suppressor sequencing. Independent variable: primer set. Dependent variable: variant calls. Controlled variable: annealing temperature. Method: identify the independent variable, dependent variable and controlled variable; keep controls constant; evaluate validity, reliability, accuracy, precision, uncertainty, risk, limitation, conclusion and improvement. Link the result to Explain how base-sequence changes can alter amino acid sequences.; transcription makes RNA and translation makes polypeptide.
- B. CGEQ64: Change primer set and annealing temperature together, then ignore uncertainty and controls.
- C. CGEQ64: Record variant calls without a method, dependent variable or evaluation.
- D. CGEQ64: Describe gene expression generally but omit the controlled variable and conclusion.
Answer
Correct answer: CGEQ64: Use tumour suppressor sequencing. Independent variable: primer set. Dependent variable: variant calls. Controlled variable: annealing temperature. Method: identify the independent variable, dependent variable and controlled variable; keep controls constant; evaluate validity, reliability, accuracy, precision, uncertainty, risk, limitation, conclusion and improvement. Link the result to Explain how base-sequence changes can alter amino acid sequences.; transcription makes RNA and translation makes polypeptide.. MCQ route 108: this exact option matches Explain how base-sequence changes can alter amino acid sequences. and should be chosen over distractors that change the mechanism, context or biological consequence.
Explanation
Reasoning route 108: For this question, start with the A-Level concept in Alteration of the sequence of bases in DNA can alter the structure of proteins, then connect it to the scenario using amino acid sequence and a clear cause-and-effect chain. The correct option is "CGEQ64: Use tumour suppressor sequencing. Independent variable: primer set. Dependent variable: variant calls. Controlled variable: annealing temperature. Method: identify the independent variable, dependent variable and controlled variable; keep controls constant; evaluate validity, reliability, accuracy, precision, uncertainty, risk, limitation, conclusion and improvement. Link the result to Explain how base-sequence changes can alter amino acid sequences.; transcription makes RNA and translation makes polypeptide.", so the explanation must explicitly support that wording. The question wording is "CGEQ64: Which experimental interpretation best tests Explain how base-sequence changes can alter amino acid sequences.…". Reasoning route 145: A precise explanation should use the context, quote or interpret any evidence, and return to Explain how base-sequence changes can alter amino acid sequences. rather than giving a generic biology statement.

The question wording is "CGEQ64: Which experimental interpretation best tests Explain how base-sequence changes can alter amino acid sequences.…". The response earns credit when it separates the named process from its effect. Here the relevant objective is Explain how base-sequence changes can alter amino acid sequences., so the explanation must stay specific. CGEQ64: The option is correct because it states method, independent variable, dependent variable, controlled variable, controls, evaluation and a valid conclusion for tumour suppressor sequencing. This also helps avoid confusing similar A-Level terms that share vocabulary but test different biological reasoning. Distractors usually fail because they reverse the mechanism, use the wrong scale of organisation, or describe a related topic without answering the exact objective.

This also helps avoid confusing similar A-Level terms that share vocabulary but test different biological reasoning. If practical wording appears, address method, independent variable, dependent variable, control variables, risk, precision, accuracy, uncertainty and evaluation.
