Replication origins are fundamental organizers and regulators of gene activity through embryonic development.

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

In addition to causing DNA damage, R-loops cause genomic instability by interfering with DNA repair.

Meiotic cells employ a specific pathway to limit the amount of gene conversion occuring at recombination sites.

Arabidopsis microRNAs and their effector protein ARGONAUTE1 associate with and act on polysomes on the rough endoplasmic reticulum.

The genome-organizer Satb2 has a key role in memory formation by modulating availability of miRNAs that control the function of synapses.

An epigenome-wide study shows that ethnic self-identification and genetically determined ancestry both make important independent contributions to DNA methylation levels.

The model organism Tetrahymena thermopile carries two nuclei with distinct genomes: an unrearranged germline genome with five chromosomes, and a somatic genome reduced in size by a third and with 181 chromosomes.

Common ancestries, activities and structural determinants of a modular (bi-)polarization control system encoded in free-living and obligate intracellular α-proteobacteria, including the rickettsial pathogens, are described.
