In their article, which was published today in Cell Reports, Brian and Helle show that the enzyme RNase H2 removes RNA-DNA hybrids primarily after DNA replication. Any remaining RNA-DNA structures ...

Statello, L., et al. (2024). The chromatin-associated lncREST ensures effective replication stress response by promoting the assembly of fork signaling factors.

Intriguing evidence for yet another role of DDX3X has emerged, this time in the context of the DNA damage response. Disruption of this helicase impairs DNA repair pathways, leading to an accumulation ...

A 2-gram chunk from this rock — a piece of the meteorite that fell near Murchison, Australia, in 1969 — contains two crucial components of DNA and RNA now identified for the first time in an ...

Scientists successfully induced gene expression from a DNA and evolution through continuous replication extracellularly using cell-free materials alone for the first time. By adding the genes ...

Until now, DNA and RNA epigenetics were studied as independent systems. These two mechanisms seemed to function separately, each playing its own role in distinct stages of the gene regulation process.

For 400 million years, a leading hypothesis claims, Earth was an “RNA World,” meaning that life must’ve first replicated from RNA before the arrival of proteins and DNA. Unfortunately ...
