Genome-wide mapping of heteroduplex DNA (a recombination intermediate) formed during mitotic recombination in yeast demonstrates that the "classical" model of double-strand DNA break repair is inadequate to explain several aspects of mitotic recombination.

Different homologous recombination pathways are dominant in different regions of meiotic chromosomes, indicating that chromosome structure influences recombination biochemistry.

In humans, non-crossover gene conversion events transmit GC alleles in 68% of cases and exhibit a complex pattern of multiple disconnected tracts clustered within 20–30 kilobase intervals.

TRF1 suppresses replication fork stalling, which triggers break induced replication at telomeres associated with DNA damage response, alteration in the telomere chromatin environment, and re-localisation of telomeres to PML bodies.
Malaria parasites avoid destruction by their host's immune response through systematic and coordinated expression switching between members of a network of variant antigen-encoding genes, a process that is mediated by a uniquely conserved gene called var2csa.
Arabidopsis deploys the core signalling module that perceives distinct stress signals, such as DNA damage and heat stresses, and represses G2/M-specific genes, thereby causing cell cycle arrest.
Loss of heterozygosity (LOH) mediated diversification of the diploid S. cerevisiae hybrid genomes during asexual propagation are vast and exceptionally varied depending on the genetic background.

Genome-wide analysis of sister chromatid exchange using single-cell sequencing reveals that most spontaneous sister chromatid exchange events are not due to the repair of double-strand DNA breaks in wild-type yeast cells.
