UT Southwestern researchers have identified a four-protein complex that appears to play a key role in generating ribosomes—organelles that serve as protein factories for cells—as well as a surprising ...

Inside tiny cellular machines called ribosomes, chains of genetic material called messenger RNAs (mRNAs) are matched with the corresponding transfer RNAs (tRNAs) to create sequences of amino acids ...

Led by Northwestern Engineering’s Michael Jewett, researchers created a new version of an engineered tethered ribosome dubbed Ribo-T, which provides a foundation to propel broad, new efforts in ...

Scientists report a method for stable attachment of peptides to tRNAs, which has allowed them to gain new fundamental insights into ribosome function by determining the atomic-level structures of ...

The discovery of ribosomes dates back to the 1950s, when George Palade first observed dense particles in the cytoplasm of cells using electron microscopy. These particles were later named "ribosomes" ...

Ribosomes are composed of two subunits, the small and large subunits, each containing specific rRNA molecules. The main types of rRNA include: Small Subunit rRNA: In prokaryotes, the small subunit ...

Inside tiny cellular machines called ribosomes, chains of genetic material called messenger RNAs (mRNAs) are matched with the corresponding transfer RNAs (tRNAs) to create sequences of amino acids ...

In a study published in Nature Communications, researchers at Karolinska Institutet have mapped key steps in the assembly of the mitochondrial ribosome, offering new clues to how defects in this ...

In the study of bacteria, a longstanding dogma has held that two molecular machines—RNA polymerase, which leads the way in ...

Systematic characterization of terminating ribosomes uncovers sequence features influencing ribosome dynamics at stop codons with direct implications in 3' UTR translation.
