Human ribosomal RNA intergenic spacer sequence.
The human rDNA tandem repeat consists of 13.3 kb of transcribed sequence and about 30 kb of intergenic spacer of unknown function. For descriptive purposes, it is convenient to divide the ribosomal repeat into 4 EcoRI fragments, A D . The C fragment contains only intergenic spacer sequences, and ends some 500 bp upstream of the ribosomal RNA promoter. We had previously described the terminal Ba...
متن کاملNucleotide sequence of the intergenic spacer and the 18S ribosomal RNA gene from mustard (Sinapis alba).
From a rRNA repeating unit (9.1 kbp) of mustard we have The DNA was sequenced according to the method of Maxam sequenced the first internal transcribed spacer, the 5.8S rRNA and Gilbert gene, and the second internal transcribed spacer [1]. Here, we present the nucleotide sequence of a 5500 bp fragment containing the 3 ' end terminus of the 25S gene (486 bp), the intergenic spacer REFERENCES (32...
متن کاملPhylogeny of Porphyromonas gingivalis by ribosomal intergenic spacer region analysis.
Periodontitis has been associated with the presence of Porphyromonas gingivalis, and previous studies have shown phenotypic differences in the pathogenicities of strains of P. gingivalis. An accurate and comprehensive phylogeny of strains of P. gingivalis would be useful in determining if there is an evolutionary basis to pathogenicity in this species. Previous phylogenies of P. gingivalis stra...
متن کاملWhere no RNA polymerase has gone before: novel functional transcripts derived from the ribosomal intergenic spacer.
The nucleolus is organized around a scaffolding of rDNA tandem repeats. These repeats, known as ribosomal cassettes, are each composed of ribosomal RNA (rRNA) genes preceding a long intergenic spacer (IGS) that has been classically perceived to be transcriptionally silent. Recent study of the IGS has contradicted the dogma that these spacers are merely inert regions of the genome, instead sugge...
متن کاملSpecies and genus specificity of the intergenic spacer (IGS) in the ribosomal RNA genes of Cucurbitaceae.
The use of intergenic spacer (IGS) fragments of plant ribosomal DNA (rDNA) for the differentiation between genera and species is tested by cross-hybridization experiments with different IGS probes of two Cucurbitaceae, Cucurbita pepo (zucchini) and Cucumis sativus (cucumber). Hybridization with cloned fragments of different parts of the IGS of ribosomal DNA exhibit a different degree of conserv...
