Description
Description
Cytoplasmic ribosomes are found on the endoplasmic reticulum and in the cytoplasm. They translate all mRNAs produced from nuclear genes and perform the majority of cellular protein synthesis. Ribosomes are formed by two ribonucleoprotein subunits, large and small. The principle function of the small subunit is to bind mRNA. (Adapted from FBrf0205398)
Notes on Group

Cytoplasmic rRNAs are multicopy genes organised in tandem arrays (FBrf0202637). 18S rRNA (18SrRNA, SO:0002236) is associated with the small cytoplasmic ribosome.
