Item 21 refers to the graph below which represents the relative amounts of DNA per nucleus during many cell divisions in an animal cell. Which of the following processes are occurring at A and B? \begin{tabular}{|l|l|l|} \hline & \multicolumn{1}{c|}{\textbf{A}} & \multicolumn{1}{c|}{\textbf{B}} \\ \hline (A) & Fertilization & Cytokinesis \\ \hline (B) & DNA synthesis & Fertilization \\ \hline (C) & Fertilization & DNA synthesis \\ \hline (D) & DNA synthesis & Separation of chromosomes \\ \hline \end{tabular}

1. (A)A: Fertilization; B: Cytokinesis
2. (B)A: DNA synthesis; B: Fertilization
3. (C)A: Fertilization; B: DNA synthesis
4. (D)A: DNA synthesis; B: Separation of chromosomes

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