Abstract
Escherichia coli nucleoids isolated in the presence of spermidine have been shown to contain DNA polymerase activity of which more than 95% was ascribed to DNA polymerase I and the rest to DNA polymerases II and III. It also has been found that DNA polymerases II and III or DNA polymerase III substituted entirely for DNA polymerase I or DNA polymerase I and II in the nucleoids isolated from E. coli mutants lacking the corresponding enzyme activities.
