Abstract:

The accurate copying of DNA is one of the most important jobs an organism must do during its life. For such an important task, cells employ not one but a whole team of enzymes. However, the star of the team is the enzyme DNA polymerase. This protein builds the new daughter strand from nucleotides in the cell and checks the new base pairs for accuracy. The other protein team members help DNA polymerase do its job. All bacteria and higher organisms and many viruses have their own DNA polymerase proteins, which are encoded by their DNA. All of these DNA polymerases work in similar ways and even resemble one another. Scientists, therefore, often study the complicated process of DNA replication in simple systems, such as bacterial and animal viruses, and apply what they have learned as they look at higher organisms. From these simple systems, many general facts about DNA polymerases have emerged.
