WebMay 7, 2024 · The cell cycle is a repeating series of events that include growth, DNA synthesis, and cell division. The cell cycle in prokaryotes is quite simple: the cell grows, its DNA replicates, and the cell divides. This form of division in prokaryotes is called asexual reproduction. In eukaryotes, the cell cycle is more complicated. WebMar 31, 2024 · Figure 1: Strand of DNA. Figure 2: Model of DNA Replication.
