Gene amplification in oocytes of the rove beetle Creophilus maxillosus (Staphylinidae, Coleoptera-Polyphaga).
The extra-DNA body was found, for the first time, in oocytes of an insect with telotrophic ovary. Dispersion of this body is accompanied by an enormous increase of nuclear volume and production of multiple nucleoli. It is suggested that the extra-DNA contains a huge mass of nucleolus organizers.
