During what phase of the cell cycle is DNA replicated?

• G1 phase

• S phase

• G2 phase

• M phase

During which phase of the cell cycle is the DNA copied?

• Metaphase

• Telophase

• Interphase

• Prophase

The model represents the change in DNA content of a cell during the cell cycle. Which part of the model represents the S phase?

• I

• II

• III

• IV

Answer explanation

Remember the cell cycle = G1, S, G2, M.

During "S" phase, your DNA replicates and makes an exact copy of itself.

The graph shows the DNA doubling during II, so II has to be the "s" phase.
