Question
- A. Use sickle-cell allele evidence to support Use binomial naming principles: gene vs allele: a gene is a DNA sequence for a product, whereas an allele is a variant version of that gene. Link the evidence to base sequence, chromosome behaviour or inheritance outcome before reaching a conclusion.
- B. Use the words from the objective without interpreting sickle-cell allele evidence or explaining molecular evidence.
- C. Swap key genetic terms freely and ignore chromosome number, base sequence and inheritance evidence.
- D. Describe the topic title only, then leave out the biological consequence.
Answer
The correct answer is: Use sickle-cell allele evidence to support Use binomial naming principles: gene vs allele: a gene is a DNA sequence for a product, whereas an allele is a variant version of that gene. Link the evidence to base sequence, chromosome behaviour or inheritance outcome before reaching a conclusion.
Explanation
This is correct because it applies the objective, Use binomial naming principles, to a named evidence source and states the boundary explicitly: gene vs allele: a gene is a DNA sequence for a product, whereas an allele is a variant version of that gene. The distractors avoid the evidence or blur terminology.
