We report a method for studying global DNA methylation based on using bisulfite treatment of DNA and simultaneous PCR of multiple DNA repetitive elements, such as Alu elements and long interspersed nucleotide elements (LINE). The PCR product, which represents a pool of approximately 15 000 genomic loci, could be used for direct sequencing, selective restriction digestion or pyrosequencing, in o...
CR1 is a short interspersed repetitive DNA element originally identified in the domestic chicken (Gallus gallus). However, unlike virtually all other such sequences described to date, CR1 is not confined to one or a few closely related species. It is probably a ubiquitous component of the avian genome, having been detected in representatives of nine orders encompassing a wide spectrum of the cl...
Many repetitive elements, for example, SINEs, LINEs, LTR-retrotransposons and other SSRs are dispersed throughout eukaryotic genomes. To understand the biological function of these repetitive elements is of great current research interest. In this study, we report on the identification of a novel non-coding DNA family, designated CE1 family, in the nematode C. elegans genome. Some CE1 elements ...
The presence of repetitive elements can create serious problems for sequence analysis, especially in the case of homology searches in nucleotide sequence databases. Repetitive elements should be treated carefully by using special programs and databases. In this paper, various aspects of SINE (short interspersed repetitive element) identification, analysis and evolution are discussed.
conclusions our results indicated that the dissemination of pi-1 was widespread in s. pneumoniae isolates, although no pi-2 isolates were detected. furthermore, the frequency of rlra and rrgc of clinical isolates was significantly more than that of normal flora isolates. results the results confirmed the presence of rlra and rrgc genes in both clinical (n = 39) and normal flora (n = 26) isolate...
