Taller 4. Ciclo celular y división celular (cap 11). DNA y su papel en la herencia (cap 13) 1. 11.1. RECAP: Four events are required for cell division: a reproductive signal, replication of the genetic material (DNA), segregation of replicated DNA, and separation of the two daughter cells (cytokinesis). In prokaryotes, cell division can be rapid; in eukaryotes, the process is more intricate, and the chromosomes must be duplicated before cell division can occur. a. What is the reproductive signal that leads the bacterium Bacillus subtilis to divide? See p. 210 b. Explain why DNA must be replicated and segregated before a cell can divide. See p. 210 c. What are the differences between cell division in prokaryotes (binary fission) and mitosis in eukaryotes? See pp. 211–212 2. 11.2 RECAP: The eukaryotic cell cycle is under both external and internal control. Cdk’s control the eukaryotic cell cycle and are themselves controlled by cyclins. External signals such as growth factors can initiat
