Further experiments on the role of the nucleolus in the transfer of RNA from nucleus to cytoplasm.
نویسنده
چکیده
The role of the nucleolus in the transfer of RNA from nucleus to cytoplasm was examined by means of experiments in which the nucleolus or other parts of the nucleus were inactivated by a microbeam of ultraviolet light. These experiments confirmed previous work in showing that such inactivation of the nucleolus inhibited the appearance in the cytoplasm, not only of ribosomal RNA, but also of other types of RNA made in the nucleus, in particular transfer RNA.

The Role of the Nucleolus in the Transfer of Rna from Nucleus to Cytoplasm
The role of the nucleolus in the transfer of RNA from nucleus to cytoplasm was examined by means of experiments in which inactivation of the whole nucleus, or of the nucleolus, was achieved by a microbeam of ultraviolet light. In heterokaryons in which a chick erythrocyte nucleus had been reactivated, no detectable amount of RNA was transferred from the reactivated nucleus to the cytoplasm of t...

RNA processing is essential factor for synthesis of functional and structural proteins in eukaryote cells. In eukaryote organisms it will be initiated with transcription of DNA in nucleolus and terminated to mRNA translation in cytoplasm, finally mRNA degraded. Protein synthesis followed as different steps, includes 5' capping, poly adenylating, processing and transferring from nucleolus to cyt...

متن کاملThe expression of genetic information: a study with hybrid animal cells.
When the nucleus of a hen erythrocyte is introduced into the cytoplasm of a human or mouse cell in culture, it resumes the synthesis of RNA. The reactivated erythrocyte nucleus undergoes great enlargement, but it does not, for at least 2 or 3 days, develop nucleoli which can be discerned under the light microscope. During this period, the heterokaryon, although it may contain several active ery...
متن کاملBeta-catenin Forms Protein Aggregation at High Concentrations in HEK293TCells
Background: The canonical Wnt signal transduction (or the Wnt/β-catenin pathway) plays a crucial role in the development of animals and in carcinogenesis. Beta-catenin is the central component of this signaling pathway. The activation of Wnt/β-catenin signaling results in the cytoplasmic and nuclear accumulation of β-catenin. In the nucleus, β-catenin interacts with the TCF/LEF transcription fa...
