The Srs2 helicase functions in Synthesis-Dependent Strand Annealing to avoid crossover formation during homologous recombination by disrupting D-loops that are extended by DNA polymerase delta in an ATP-dependent and direction-specific manner.

Molecular beacon based FISH shows the capability of visualizing a 2.5 kb non-repetitive genomic DNA sequence in situ in human or mouse nuclear genome at super resolution.

Systematic analyses of natural variants and artificial mutants establish functional landscapes of BRCA1 for homology-directed repair (HDR) and therapy resistance and identify the BRCA1-PALB2 interaction as a key control point for HDR pathway choice.

PLK-1/2-mediated SYP-4 phosphorylation is dependent on crossover precursor formation, triggering a switch in the dynamic state of the synaptonemal complex that reduces the formation of further double-strand breaks at late meiotic prophase.

The scaffolding that holds chromosome pairs together plays a key role in limiting the levels of double-strand breaks.

Small regulatory RNAs are able to modulate mRNA degradation rates by controlling access to the 5' end of mRNAs in bacteria.

The guide RNA and donor DNA of the CRISPR/Cas system tolerate large chemical modifications and can be engineered for enhanced delivery and gene editing.

ChIP-seq and phenotypic analyses reveal Atrophin from Drosophila directly regulates Notch and Dpp signaling components, and engrailed gene expression, via interactions with GAGA Factor.

Promoter interactome maps in human embryonic stem cells (ESCs) and ESC-derived early neuroectodermal progenitors link distal enhancers to putative target genes, reveal lineage-specific cis-regulatory architecture and shed light on the logic of gene regulation by multiple enhancers.

Post-translational modification of histone H3K36 is not required to suppress cryptic transcription initiation or to include alternative exons in Drosophila; instead it promotes expression of active genes by stimulating polyadenylation.
