All prokaryotes have 70S (where S=Svedberg units) ribosomes while eukaryotes contain larger 80S ribosomes in their cytosol. The 70S ribosome is made up of a 50S and 30S subunits.

Prokaryotic ribosomes are composed of two subunits: a small 30S subunit and a large 50S subunit. Together, they form a 70S ribosome. The S in 70S stands for Svedberg units, which is a measure of the sedimentation rate of the ribosome.

The 30S subunit contains a single RNA molecule, called 16S rRNA, and 21 proteins. The 50S subunit contains two RNA molecules, called 5S rRNA and 23S rRNA, and 34 proteins.

The ribosome is responsible for protein synthesis in the cell. It reads the genetic code in mRNA and uses it to assemble amino acids into a protein chain. The 70S ribosome is smaller than the eukaryotic ribosome, which is composed of a 40S and a 60S subunit (forming an 80S ribosome).

In summary, prokaryotic ribosomes are 70S ribosomes composed of a 30S subunit and a 50S subunit.
