Summary
-
1.
The kinetics of RNA synthesis in nucleate and enucleated cells ofAcetabularia mediterranea have been compared.
-
2.
Nucleate cells and cells 24 hours after enucleation show no differences in their kinetics nor in the sedimentation behavior of the newly-synthesized RNA isolated after various short intervals (≦120 min) of incubation in the presence of tritiated ribonucleosides which can be attributed to enucleation. This fact is explained by predominant extranuclear RNA synthesis.
-
3.
The kinetics of the synthesis of the 23 s and 16 s ribosomal RNA peaks suggest that each of these peaks may be composed of two components. The possible origin of these components is discussed.
