A macromolecular complex containing both protein and RNA molecules. Any complex of pre-rRNAs, ribosomal proteins, and associated proteins formed during ribosome biogenesis. A heterodimer associated with precursors of the eukaryotic small ribosomal subunit, including the 90S preribosome; involved in small subunit biogenesis. A preribosomal complex consisting of 20S pre-rRNA, ribosomal proteins including late-associating small subunit proteins, and associated proteins; a precursor of the eukaryotic cytoplasmic small ribosomal subunit.
