In prokaryotes, ribosomes are composed of small (_____) and large (_____) subunits, forming a _____ ribosome.

Explanation:
In prokaryotes, ribosomes are defined by how they sediment in a gradient, not by a simple count of atoms. The functional ribosome is made of two subunits: a small subunit that sediments at 30S and a large subunit that sediments at 50S. Together, they form the 70S ribosome used for protein synthesis in the cytoplasm. This contrasts with eukaryotic cytosolic ribosomes, which are 80S and built from a 40S small subunit and a 60S large subunit.
