Cell Structure: The Ribosome

Ribosomes are made up of two large complexes comprised of RNA and protein. Ribosomes are located in the cytosol and are quite numerous. They are responsible for reading RNA and using the encoded information to produce proteins in a process called translation. Translation is discussed in more detail in the Gene Function section.

The diagram below shows the two ribosomal subunits (large and small) bound to a messenger RNA (mRNA).
