CAPE Biology Unit 1 · 2011 · Paper 2 · Question 1(a)(v)

Figure 1 shows an incompletely labeled diagram of a prokaryotic cell, including a ribosome, cytoplasm, and cell surface membrane.

Both eukaryotic cells and prokaryotic cells contain DNA. State ONE way in which the DNA in eukaryotic cells differs from the DNA in prokaryotic cells.

This question uses a figure or table from the paper — you'll see it when you practise.
