[Functional organization of the chromomere. II. Effect of choriogonin on RNA synthesis within the limits of the functioning chromomere].

With the aid of 3-H-uridine radioautography, the effect of gonadotropic hormone choriogonin on the synthesis of RNA in the giant granular loop of XII chromosome of the Triturus cr. cristatus oocytes was studied in normal and after pretreatment of the cells with mutagen. Choriogonin, while obviously stimulating the RNA synthesis, has no effect on the cells pretreated with mutagen.
