![]() DNA replication occurs only during a specific stage of the cell cycle. But the replication of each eukaryotic DNA molecule is similar to replication in prokaryotes, in that it is achieved by threading the long strands through replication complexes (see Concept 9.2). Unlike prokaryotes, eukaryotes have more than one chromosome. We will discuss the signals that control eukaryotic cell division in Concept 7.3. ![]() In a eukaryotic organism, the signals for cell division are usually not related to the environment of a single cell, but to the function of the entire organism. In fact, most cells in a multicellular organism are specialized and do not divide. Unlike prokaryotes, eukaryotic cells do not constantly divide whenever environmental conditions are adequate. Some of the details, however, are quite different: Let’s see how these events occur during the processes of binary fission in prokaryotes and mitosis in eukaryotes.Įukaryotic cells divide by mitosis followed by cytokinesisĪs in prokaryotes, cell division in eukaryotes entails reproductive signals, DNA replication, DNA segregation, and cytokinesis.
