Abstract
It has been found that the transcriptional activity of nuclear extra DNA inCreophilus maxillosus oocytes, as examined by autoradiography, increases parallel with its dispersion during the previtellogenic period of oocyte growth. The RNA, after being synthesized in the greatly enlarged oocyte nucleus, is subsequently transported into the cytoplasm. The oocyte chromosomes form a karyosphere and synthesize the RNA more weakly than other parts of the nucleus, which contain the extra DNA in a highly dispersed condition.Keywords
