title: Characterization of the 42-S nucleoprotein particles of Cyprinus carpio oocytes.
abstract: Previtellogenic oocytes of the fish Cyprinus carpio contain 42S nucleoprotein particles that are composed of two proteins of molecular weights 48,500 and 39,300 (molar ratio 2:1), tRNA and 5S RNA (molar ratio 3:1). The tRNA population embodied in the 42S particle contains all amino acid acceptor species but their distribution differs from that found in tRNA from mature oocytes.
