Editing Polysome (section)

=== Prokaryotic ===
Bacterial polysomes have been found to form double-row structures. In this conformation, the ribosomes are contacting each other through smaller subunits. These double row structures generally have a “sinusoidal” (zigzag) or 3-D helical path. In the “sinusoidal” path, there are two types of contact between the small subunits- “top-to-top” or “top-to-bottom”. In the 3-D helical path, only “top-to-top” contact is observed.<ref name=":0" />

Polysomes are present in archaea, but not much is known about the structure.<ref>{{cite journal | vauthors = French SL, Santangelo TJ, Beyer AL, Reeve JN | title = Transcription and translation are coupled in Archaea | journal = Molecular Biology and Evolution | volume = 24 | issue = 4 | pages = 893–5 | date = April 2007 | pmid = 17237472 | doi = 10.1093/molbev/msm007 | doi-access = free }}</ref>
