Anand et al. examined break-induced replication (BIR) and template switching between highly diverged sequences in S. cerevisiae, induced during repair of a site-specific double-strand break (DSB). Template switches between highly divergent sequences appear to be mechanistically distinct from the initial strand invasions that establish BIR. BIR traversing repeated DNA sequences frequently results in complex translocations analogous to those seen in mammalian cells. These results suggest that template switching among repeated genes is a potent driver of genome instability and evolution.
