Ribosome crystals in the oocyte of Gerris najas (Heteroptera).
Oocytes of the pond skater, Gerris najas, display ribosome tetramers that are arranged in the form of sheets in the vicinity of the nucleus. This is the first finding of ribosome crystals in an insect and suggests that ribosome crystallization may be a common phenomenon of cells that are inactive in protein synthesis.
