What Are Unattached Ribosomes in the Cytosol?


Quick Answer

Unattached ribosomes, also known as free ribosomes, are described by Seattlepi as intracellular bodies that initiate protein synthesis by translating messenger RNA. These bodies float freely in the cytosol. The mRNA that is translated by the unattached ribosomes stays in the cytosol.
