Question

In the eukaryotic cell cycle, cell fusion experiments show that:

Options

• when an S-phase cell is fused with a G₁-phase cell, G₁-phase cell is stimulated to synthesize DNA

• when an S-phase cell is fused with a G₁-phase cell

• when a G₁-phase cell is fused with a G₁-phase cell, DNA synthesis is induced in both G₁ and G₂ phase cells

• when a G₁-phase cell is fused with an M-phase

Answer 1

when an S-phase cell is fused with a G₁-phase cell, G₁-phase cell is stimulated to synthesize DNA
