| Abstract: | Zinc ion was found in various kinds of polymerases and involved in the activation of the 3'-hydroxyl group of primer chain's growing end. In order to investigate whether zinc ion was selected for nucleotide synthesizing system inevitably or by historical accident, ab initio molecular orbital calculations were carried out and the results suggest that zinc ion may have been selected inevitably. |
