Question

  1. A. CGEQ2: Use methylation PCR gel. Independent variable: bisulfite treatment. Dependent variable: band intensity. Controlled variable: DNA mass loaded. 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 Interpret mutation information in unfamiliar contexts.; transcription makes RNA and translation makes polypeptide.
  2. B. CGEQ2: Change bisulfite treatment and DNA mass loaded together, then ignore uncertainty and controls.
  3. C. CGEQ2: Record band intensity without a method, dependent variable or evaluation.
  4. D. CGEQ2: Describe gene expression generally but omit the controlled variable and conclusion.

Answer

The correct answer is: CGEQ2: Use methylation PCR gel. Independent variable: bisulfite treatment. Dependent variable: band intensity. Controlled variable: DNA mass loaded. 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 Interpret mutation information in unfamiliar contexts.; transcription makes RNA and translation makes polypeptide.

Explanation

This works because the answer is anchored to Interpret mutation information in unfamiliar contexts.: 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. CGEQ2: The option is correct because it states method, independent variable, dependent variable, controlled variable, controls, evaluation and a valid conclusion for methylation PCR gel. Distractors usually fail because they reverse the mechanism, use the wrong scale of organisation, or describe a related topic without answering the exact objective.
