WebOur present understanding of its structure, function and dynamics is the result of six decades of research. This book collects over 40 articles based on the talks presented at the 2010 Ribosome Meeting, held in Orvieto, Italy, covering all facets of the structure and function of the ribosome. WebEach ribosome is composed of a large and a small subunit. Ribosomal subunits are made in the nucleolus and then exported into the cytoplasm, where they pair off to form whole ribosomes. Often several ribosomes are translating a given mRNA molecule simultaneously; such a structure is called a polysome.
