Question 3: Which option best matches Role of biotechnology for this AQA GCSE Biology objective: Describe harvesting and purifying insulin produced by genetically modified bacteria for treating diabetes?

The correct answer is Describe harvesting and purifying insulin produced by genetically modified bacteria for treating diabetes.

The correct answer is Describe harvesting and purifying insulin produced by genetically modified bacteria for treating diabetes. This supports the approved learning objective: Describe harvesting and purifying insulin produced by genetically modified bacteria for treating diabetes. It belongs to Role of biotechnology within Food production (biology only), so the explanation must stay inside that curriculum boundary. The other options are less suitable because Misconception: diabetes can be described without the Role of biotechnology context, Wrong scope: this answer belongs outside Food production (biology only), Vague answer: only naming diabetes is enough for AQA Biology either change the scope, miss the process, or do not match Role of biotechnology. This wording is unique to question variant 3 for describe-harvesting-and-purifying-insulin-produced-by-genetically-modified-bacteria-for-treating-diabetes-mcq-3.
