Transcription beyond annotated gene boundaries expands the diversity of the cancer transcriptome with overexpressed oncogenes and RNA chimeras.

Upon genotoxic stress, the FBXL10-RNF68-RNF2 ubiquitin ligase complex mono-ubiquitylates histone H2A and mediates H2A/H2A.Z exchange to repress transcription and ensures proper high fidelity homologous recombination repair.

The accumulation of carbon black nanoparticles in smokers' lungs causes sterile inflammation, double-strand DNA breaks and emphysema.

RNA molecules cause the proteins involved in the formation of germ granules to coalesce into liquid droplets.

Structures known as chromocenters, comprising satellite DNA and proteins such as D1 or HMGA1, help to contain DNA inside the nucleus between cell divisions.

Some RNAs in mammalian cells can help to silence the DNA they are transcribed from.

An artificially evolved ribozyme can catalyse the synthesis of RNA by using trinucleotide triphosphates as building blocks.

In rotaviruses, the selective packaging of eleven distinct genomic RNA segments requires virus-encoded protein NSP2 to alter the RNA structures, facilitating their interactions with each other.

The discovery of a mechanism that causes DNA deletions during non-canonical DNA replication termination is described.

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