Characterization of the 42-S nucleoprotein particles of Cyprinus carpio oocytes.
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.
