1S0V - PubMed Abstract: 
The mechanism by which nucleotide polymerases select the correct substrate is of fundamental importance to the fidelity of DNA replication and transcription. During the nucleotide addition cycle, pol I DNA polymerases undergo the transition from a catalytically inactive "open" to an active "closed" conformation ...
