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.

Researchers have developed a new microscopy technique to observe how ribosomes function in cells. With this method, they can monitor individual ribosomes as they convert mRNA into proteins.

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 ...
