In eukaryotic cell cycle, cell fusion experimetns show that

Options

A. When an S-phase cell is fused with a `G_(1)` -phase cell, `G_(1)` - phase cell is stimulated to synthesize DNA
B. When an S-phase cell is fused with a `G_(2)` -phase cell, DNA synthesis is induced in `G_(2)` -phase cell
C. When a `G_(1)` -phase cell is fused with a `G_(2)` -phase cell, DNA synthesis is induced in both `G_(1) and G_(2)` phase cells
D. When a `G_(1)` -phase cell is fused with an M-phase cell both `G_(1)` and M phase cells are stimulated to synthesize DNA

Answer

B

Explanation

Conclusion: - S phase nucleus release something that drives `G_(1)` Phase into S – phase
