Study finds mysterious DNA split in great white sharks defies current explanations

White sharks (Carcharodon carcharias) almost went bottom-up during the last ice age, when sea levels were much lower than they are today and sharks had to get by with less space. The most recent cold snap ended about 10,000 ...

Research reveals spatiotemporal coordination between pre-rRNA processing and nucleolar architecture

In eukaryotic cells, the nucleolus is the central site for ribosome biogenesis. It is composed of distinct subcompartments: fibrillar center (FC), dense fibrillar component (DFC), periphery of DFC (PDFC), and granular component ...
