Sequence-specific cleavage of RNA in the absence of divalent metal ions by a DNAzyme incorporating imidazolyl and amino functionalities.
Two modified 2'-deoxynucleoside 5'-triphosphates have been used for the in vitro selection of a modified deoxyribozyme (DNAzyme) capable of the sequence-specific cleavage of a 12 nt RNA target in the absence of divalent metal ions. The modified nucleotides, a C5-imidazolyl-modified dUTP and 3-(aminopropynyl)-7-deaza-dATP were used in place of TTP and dATP during the selection and incorporate tw...
متن کاملthe evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
15 صفحه اولSite specific functionalization of oligonucleotides for attaching two different reporter groups.
The synthesis of an oligonucleotide functionalized to attach two different reporter groups at specific internucleotide linkages is described. To incorporate the amine specific reporter group the internucleotide linkage is modified to phosphoramidate (N-1-aminoalkyl) and for a thiol specific reporter group the internucleotide linkage is modified to a phosphorothioate diester. The synthetic cycle...

Site specific labelling of sugar residues in oligoribonucleotides: reactions of aliphatic isocyanates with 2' amino groups.
Considerable effort has been directed towards studying the structure and function of nucleic acids and several approaches rely on the attachment of reporter groups or reactive functional groups to nucleic acids. We report here the selective modification of 2-amino groups in oligoribonucleotides, through their reaction with aliphatic isocyanates, to give the corresponding 2'-urea derivatives in ...
