title: Fine structure of the 30 S ribosomal subunit.
abstract: Elongated hollow strands were revealed on raw images and averaged by the correlation method images of the 30 S subunit of the E. coli ribosome negatively stained by uranyl acetate. The tentative three-dimensional arrangement of the 'strands' and their nature are discussed.
