A comparison of the main features of these two categories of cell is shown in the table discussed, but other differences do occur Although the basic mechanisms of DNA replication, RNA synthesis and protein synthesis are the same in both prokaryotes and eukaryotes, there are differences in the components and enzymes involved. These are discussed in the appropriate topics
