Question

Quizplus · Accepted Answer

Both free ribosomes in the cytosol and ribosomes bound to the ER membrane have the same types of large and small subunits. This is because ribosomes are composed of two subunits, the large subunit and the small subunit, and both types of ribosomes contain the same types of each subunit.
