    摘要: The subject invention provides for a method of selectively cloning homoduplex nucleic acid molecules, in particular, by using a strain of host cells that contains a conditionally expressed and/or conditionally active mismatch-recognizing enzyme, e.g., a temperature sensitive variant of the gene encoding the endonuclease VII from phage T4. Using this host strain, the invention features a novel cloning method that selects for PCR products that are devoid of PCR-generated mutations.
