An oligonucleotide was circularized around double-stranded DNA thanks to triple helix formation. Short oligonucleotides are known to be able to form DNA triple helices by binding into the DNA major groove at an oligopurine.oligopyrimidine sequence. After sequence-specific recognition of a double-stranded DNA target through triple helix formation, the ends of the triplex-forming oligonucleotide ...

in this study, the bacterial diversity in the activated sludge system of a full-scale municipalwastewater treatment plant in dubai was monitored over a period of one year using ribosomal rna (rrna)targeted oligonucleotide probes for a defined phylogenetic group of bacteria by the fluorescence in situhybridization (fish) technique. the largest fraction of the bacterial community in the sludge sa...

This paper reports the highlights of a user study which gauges reactions to a variety of common “trust indicators” – such as logos, third party endorsements, and padlock icons – over a selection of authentic and phishing stimuli. In the course of the think-aloud protocol, participants revealed different sensitivities to email messages and web pages. Our principal result is the analysis of what ...
