Can you spot the two ideas the mark scheme needs for full marks?

This 2-mark question is testing whether you can explain the nucleus in two linked steps. One mark comes from stating that the nucleus contains genetic material, DNA. The other mark comes from explaining why that matters: it controls cell activities by directing protein synthesis. To secure both marks, your answer needs both the genetic material point and the control of cell activities point.

Quick takeaway: For full marks: nucleus contains DNA, and that DNA controls cell activities by directing protein synthesis.

GCSE Biology revision focus: nucleus function and mark-scheme points

For AQA GCSE Biology revision, this question is a useful check on whether you can turn basic cell knowledge into a 2-mark explanation. In Key Idea 1, the mark scheme is looking for exact biological points rather than a vague statement that the nucleus is 'important'. In this GCSE Biology questions and answers style of practice, focus on the wording that earns credit: genetic material (DNA), then control of cell activities by directing protein synthesis.
