Fidelity of homologous recombination in vaccinia virus DNA.

Abstract

The fidelity of homologous recombination in vaccinia virus (VV) DNA was examined by constructing a viral recombinant whose genome contained a copy of the Escherichia coli lac z gene in which the central third of the gene was repeated on either side of the VV thymidine kinase (tk) gene. In this virus, homologous DNA recombination and consequent excision of… (More)
