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 ...
Deep within the nucleus of every cell lies a structure smaller than a pinpoint that may hold the secret to aging. Scientists at Weill Cornell Medicine have discovered that the nucleolus, long known ...
TREx Expansion microscopy image of the nucleolus in a parvovirus-infected cell nucleus. The distribution of chromatin (cyan), viral protein (magenta), nucleolar fibrillarin (yellow), and total protein ...
RNA, or ribonucleic acid, is a short-lived molecule copied from DNA that enables cells to use genetic information. Specific DNA sequences are copied into RNA, which then delivers these instructions to ...
