The invention is in the field of regulation of enzymatic activity in nucleic acid modifying reactions. It describes a method of regulating enzymatic activity by adding chelating agents to the reaction composition and exploits the fact that both the binding of divalent cations to these chelating agents and the pH of commonly used buffers is temperature dependent. PCR experiments that are hampered by non-specific side products can be regulated such that the target sequence is amplified in a more specific manner.

Provided herein are a probe capable of simultaneously detecting a virus and treating virus-infected cells, a composition for detecting a virus, which comprises the probe, a composition for treating a virus, which comprises the probe, and a method of detecting a virus or treating a viral infection by using the same. According to the present disclosure, it is possible to simultaneously perform diagnosis by virus detection and treatment of virus-infected cells, and in particular, diagnosis and treatment may be simultaneously performed on various types of viruses by varying the type of molecular beacon, and thus may be usefully applied to virus diagnosis and treatment fields, which require rapid diagnosis and treatment, and the spread of viral infections may be effectively prevented. In addition, the probe of the present disclosure has excellent stability and excellent detection sensitivity, and thus enables the detection of even a very low amount of a target at the pmole level.
