| Abstract: | The insect-hormone ecdysterone causes a de novo synthesis of RNA in the fat body cells of blowfly larvae. Hybridization of the RNA induced by the hormone with 3H-Poly(U) demonstrates that it contains poly(A) sequences and therefore is probably informational. DNA-RNA-hybridization experiments further show that qualitatively new mRNA species are synthesized under the influence of ecdysterone. The inducibility of RNA synthesis is strongly correlated to specific developmental stages. |
