Analysis of transcription of the human Alu family ubiquitous repeating element by eukaryotic RNA polymerase III.
A series of clones that contain human Alu family elements are actively transcribed in soluble in vitro RNA polymerase III systems. The 5' ends of the in vitro transcripts are located about 170 nucleotides upstream of the eponymous Alu I site of the repeat, while a region associated with specifying of the initiation site for in vitro transcription lies in the region between 79 and 106 nucleotide...
متن کاملEnhancement of RNA Interference Effect in P19 EC Cells by an RNA-dependent RNA Polymerase
Background: RNA interference (RNAi) is a phenomenon uses double-stranded RNA (dsRNA) to specifically inhibit gene expression. The non-specific silencing caused by interferon response to dsRNA in mammalian cells limits the potential of utilizing RNAi to study gene function. Duplexes of 21-nucleotide short interfering dsRNA (siRNA) inhibit gene expression by RNAi. In some organisms, siRNA can als...
متن کاملIdentification of RNA polymerase III-transcribed Alu loci by computational screening of RNA-Seq data
Of the ∼ 1.3 million Alu elements in the human genome, only a tiny number are estimated to be active in transcription by RNA polymerase (Pol) III. Tracing the individual loci from which Alu transcripts originate is complicated by their highly repetitive nature. By exploiting RNA-Seq data sets and unique Alu DNA sequences, we devised a bioinformatic pipeline allowing us to identify Pol III-depen...
متن کاملthe role of task-based techniques on the acquisition of english language structures by the intermediate efl students
this study examines the effetivenss of task-based activities in helping students learn english language structures for a better communication. initially, a michigan test was administered to the two groups of 52 students majoring in english at the allameh ghotb -e- ravandi university to ensure their homogeneity. the students scores on the grammar part of this test were also regarded as their pre...
15 صفحه اولFunctional mRNA can be generated by RNA polymerase III.
Eukaryotic cellular mRNA is believed to be synthesized exclusively by RNA polymerase II (pol II), whereas pol I produces long rRNAs and pol III produces 5S rRNA, tRNA, and other small RNAs. To determine whether this functional differentiation is obligatory, we examined the translational potential of an artificial pol III transcript. The coding region of the human immunodeficiency virus type 1 t...
