Proteins are the infinitely varied chemicals that make cells work, and science has a pretty good idea how they are made. But a critical aspect underlying the machinery of protein manufacture has long ...

Chinese scientists have made a fundamental breakthrough in the understanding of the nucleolus, a structure with important functions in the nucleus. Their findings may also pave the way for diagnoses ...

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

Ribosomes carry out the cell’s most essential function—translating genetic information into proteins. But even though scientists understand much about how these protein generators are formed, their ...

The secret to cellular youth may depend on keeping the nucleolus—a condensed structure inside the nucleus of a cell—small, according to Weill Cornell Medicine investigators. The findings were ...
