Researchers at University of Tsukuba have developed a new model that simulates the internal environment of a ribosome—the cellular site of protein synthesis. Using computer simulations ...

Just as Powell was beginning work on testing his model, he had a stroke of luck: The authors of a groundbreaking new study that visualized, for the first time, ribosomes inside cells at near ...

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 ...

During translation, multiple ribosomes travel along the nucleic acid chain to build polypeptides that become functional proteins. Occasionally, these molecular decoders pause on the mRNA, either ...

A previously unknown kind of ribosome is responsible for folding sperm proteins, which decay before fertilization if prepared by other ribosomes. Dan is a News Editor at The Scientist. He writes and ...
