"Webbprokaryotes, the large subunit is called 50S and the small subunit is called 30S. The 30S subunit consists of a single strand of RNA (the 16S rRNA, 1542 bases), and proteins ranging in molecular weight from 9 kD to 61 kD. The 30S subunit can exist independently from the 50S subunit and be reconstituted from its components in vitro. " - Ribosome large subunit function
