Homologous recombination (HR) is central to the template-based repair of DNA double-strand breaks, maintaining genome integrity 1,2,3,4. A central reaction in HR is the strand exchange, in which the ...
During homologous recombination, Rad51 forms a nucleoprotein filament on single-stranded DNA to promote DNA strand exchange. This filament binds to double-stranded DNA (dsDNA), searches for homology, ...
A 45-nucleotide strand of RNA can now synthesize both its mirror-image complement and a copy of itself, bringing scientists closer than ever to demonstrating how life could have emerged from chemistry ...
