Prokaryotes have 3 varieties of rRNA: 5S, 16S and 23S rRNAs. The 5S and 23S rRNAs are found within the large ribosomal subunit, while the 16S rRNA is located in the small ribosomal subunit. Eukaryotes, on the other hand, have at least 4 flavors of rRNA: 5S, 5.8S, 18S and 28S rRNAs.

WebRNA molecules are produced in the nucleus of human cells from DNA by a process called transcription, but they are found in the cytoplasm too. DNA is present only in the nucleus of the cell.
