Biologists discovered that a scaffolding protein called TCOF1 is responsible for the formation of a biomolecular condensate called the fibrillar center, which forms within the cell nucleolus. Inside ...

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 ...

Gear-obsessed editors choose every product we review. We may earn commission if you buy from a link. Why Trust Us? More than a decade of research shows that the nucleolus—the largest structure in the ...

This model of the nucleus with nucleolus (pink) shows how ribosomal DNA is correctly repaired in young cells. In old cells with enlarged nucleolus, however, DNA repair is inaccurate leading to faster ...

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 ...
