A snurposome is a granular structure in the nuclei of amphibian oocytes. Snurposomes contain
snRNP
snRNPs (pronounced "snurps"), or small nuclear ribonucleoproteins, are RNA-protein complexes that combine with unmodified pre-mRNA and various other proteins to form a spliceosome, a large RNA-protein molecular complex upon which splicing of pre- ...

A B snurposome is composed of thousands of particles which have diameters between 20 and 30 nanometers. B snurposomes may be forms of
splicing speckles.
