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 ...

Figure 5: Model for transfer RNAs bound to the 70S ribosome, as determined by difference maps in the 70S structure. Ribosomes were first visualized in electron micrographs in 1943 (ref.

Ribosomes are the sites in a cell in which protein synthesis takes place. Cells have many ribosomes, and the exact number depends on how active a particular cell is in synthesizing proteins.

As a eukaryote, it's in many ways similar to human cells, so biologists often use it as a model organism to study fundamental cellular processes. Ribosomes turn upside-down in hungry cells ...

Only recently has the ribosome—one of the oldest molecular machines in evolutionary terms—been recognized as an active regulator of gene expression at the level of protein biosynthesis.

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 ...

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 ...
