Question

  1. A. CGEQ88: 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 mutations can affect phenotype.; transcription makes RNA and translation makes polypeptide.
  2. B. CGEQ88: Change primer set and annealing temperature together, then ignore uncertainty and controls.
  3. C. CGEQ88: Record variant calls without a method, dependent variable or evaluation.
  4. D. CGEQ88: Describe gene expression generally but omit the controlled variable and conclusion.

Answer

Correct answer: CGEQ88: 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 mutations can affect phenotype.; transcription makes RNA and translation makes polypeptide.. MCQ route 118: this exact option matches Explain how mutations can affect phenotype. and should be chosen over distractors that change the mechanism, context or biological consequence.

Explanation

Reasoning route 118: 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 phenotype, mutation and a clear cause-and-effect chain. The correct option is "CGEQ88: 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 mutations can affect phenotype.; transcription makes RNA and translation makes polypeptide.", so the explanation must explicitly support that wording. The question wording is "CGEQ88: Which experimental interpretation best tests Explain how mutations can affect phenotype. using tumour…". Reasoning route 156: This works because the answer is anchored to Explain how mutations can affect phenotype.: it names the biological idea, applies it within Alteration of the sequence of bases in DNA can alter the structure of proteins, and links the evidence to a consequence. The question wording is "CGEQ88: Which experimental interpretation best tests Explain how mutations can affect phenotype. using tumour…".

The question wording is "CGEQ88: Which experimental interpretation best tests Explain how mutations can affect phenotype. using tumour…". The response earns credit when it separates the named process from its effect. Here the relevant objective is Explain how mutations can affect phenotype., so the explanation must stay specific. CGEQ88: The option is correct because it states method, independent variable, dependent variable, controlled variable, controls, evaluation and a valid conclusion for tumour suppressor sequencing. If data are provided, the answer should identify the pattern first and then explain the biological significance. This also helps avoid confusing similar A-Level terms that share vocabulary but test different biological reasoning.

This also helps avoid confusing similar A-Level terms that share vocabulary but test different biological reasoning. If data are provided, the answer should identify the pattern first and then explain the biological significance. If practical wording appears, address method, independent variable, dependent variable, control variables, risk, precision, accuracy, uncertainty and evaluation.

Common mistake
