Small nucleolar rna small nuclear rna
WebEukaryotic cells contain a large number of U small nuclear RNAs (U-snRNAs) involved in various RNA processing reactions in the nucleoplasm and nucleous. Most of the U-snRNAs have 5'-terminal caps added to the end of the primary transcript. Here we describe two variants of a snRNA, called U17, identified in human HeLa cells. WebThe mechanism of nuclear translocation and whether N associates with particular nucleolar components are unknown. In the present study, we show by confocal microscopy that the …
