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.

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 ...
