As larger-scale cloning projects become more prevalent, there is an increasing need for comparisons among high fidelity DNA polymerases used for PCR amplification. All polymerases marketed for PCR applications are tested for fidelity properties (i.e., error rate determination) by vendors, and numerous literature reports have addressed PCR enzyme fidelity. Nonetheless, it is often difficult to m...

The balance between exonuclease and polymerase activities promotes DNA synthesis over degradation when nucleotides are correctly added to the new strand by replicative B-family polymerases. Misincorporations shift the balance toward the exonuclease site, and the balance tips back in favor of DNA synthesis when the incorrect nucleotides have been removed. Most B-family DNA polymerases have an ex...

  Background and Objective: Sinusitis is one of the most common hygienic problems and a large part of the budget has been allocated to its diagnosis and treatment yearly. In this study, the presence of cytomegalovirus in sinuses of patients, undergone operation for treatment, with or without sinusitis, was studied. Materials and Methods: This study was an applied and case-co...
