Recombination is an important process that influences biological evolution at many different levels. More and more homologous recombination events have been reported among negative sense RNA viruses recently. While sporadic authentic examples indicate that homologous recombination does occur, recombination seems to be generally rare or even absent in most negative sense RNA viruses, and most of...
Homologous recombination is a universal mechanism that allows DNA repair and ensures the efficiency of DNA replication. The substrate initiating the process of homologous recombination is a single-stranded DNA that promotes a strand exchange reaction resulting in a genetic exchange that promotes genetic diversity and DNA repair. The molecular mechanisms by which homologous recombination repairs...
PURPOSE Hallmarks of germline BRCA1/2-associated ovarian carcinomas include chemosensitivity and improved survival. The therapeutic impact of somatic BRCA1/2 mutations and mutations in other homologous recombination DNA repair genes is uncertain. EXPERIMENTAL DESIGN Using targeted capture and massively parallel genomic sequencing, we assessed 390 ovarian carcinomas for germline and somatic lo...
It has been observed that AU-rich sequences form homologous recombination hot spots in brome mosaic virus (BMV), a tripartite positive-stranded RNA virus of plants (P. D. Nagy and J. J. Bujarski, J. Virol. 71:3799-3810, 1997). To study the effect of GC-rich sequences on the recombination hot spots, we inserted 30-nucleotide-long GC-rich sequences downstream of AU-rich homologous recombination h...
