Polymerase evolution and organism evolution.
The continuing exploration of the structure-function relationships of polymerases and the use of polymerases as phylogenetic tools complement each other, as seen in the literature for the past year. DNA-dependent RNA-polymerase gene sequences, in particular, have been used both to define functional domains in the protein encoded and recently to explore fundamental questions in evolution.
