In a new study published in Cell Reports, researchers at the University of Freiburg reveal how a disordered protein segment helps connect two key steps of gene expression: the reading of genes and the ...

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 ...

Researchers demonstrated how amino acids could spontaneously attach to RNA under early Earth-like conditions using thioesters, providing a long-sought clue to the origins of protein synthesis. This ...

Biology textbooks explain that cells follow a universal rule when processing gene transcripts to make proteins. Non-coding snippets of RNA are bracketed by a guanine-thymine (GT) nucleotide sequence ...

Long before dinosaurs munched on leafy greens or photosynthesizing algae soaked up the sun, a lifeless soup of simple molecules floated through the watery and rocky landscape of early planet Earth.
