RNA synthesis in the ovarian follicle cells of Periplaneta americana during vitellogenesis.
The RNA and DNA pattern in the follicle cells of cockroach ovary during vitellogenesis has been studied. Evidences indicate that there is an active synthesis of these two nucleic acids in the nucleus. It has been suggested from the observations presented that RNA is synthesized in the chromosomes and are then transported to nucleolus before being sent to the cytoplasm. It is also shown that the follicle cells do not contribute any RNA material to the vitellogenic oocyte.
