Deoxyribonucleic acid polymerase from Landschütz ascites-tumour cells

Abstract

PROCEEDINGS OF THE BIOCHEMICAL SOCIETY sharply, the increase corresponding to the decline in radioactivity in the acid-soluble fraction. Taken in conjunction with the results described by Billing, Barbiroli & Smellie (1969), these results suggest that there are no major changes in the rate of synthesis of RNA in rat uterus until at least 6 hr. after hormone treatment and that thereafter there is a sharp increase in the rate of synthesis of RNA. These findings are consistent with the observation that the amount of RNA in rat uterus only begins to increase about 7 hr. after oestradiol treatment.
