Storing genetic material as DNA or RNA is all well and good for life on Earth, but it would be entirely pointless if we ...

Most hypotheses suggest that earlier forms of life had partial genetic codes and used fewer than 20 amino acids. To test ...

Starving yeast cells create a protective barrier in mitochondria that could reveal how cancer survives and resists treatment ...

Angiogenin is a well-characterized enzyme that has a variety of important roles; it can trigger the growth of new blood vessels, is involved in cell survival, migration, and proliferation, and has ...

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 ...

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" ...

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 ...

Scientists have pinpointed the enzyme YcaO as responsible for a rare ribosomal protein modification in several pathogenic bacteria, a process absent in humans. The finding could open new avenues for ...

A new technique reveals ribosome cooperativity, providing new insights into protein production. Researchers from Marvin Tanenbaum’s group at the Hubrecht Institute (Utrecht, Netherlands) have ...

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 part in ...
