By automated synthesis, we prepd. hybrid oligonucleotides consisting of covalently linked RNA and p-DNA sequences (p-DNA = 3'-deoxyribopyranose (4'->2')-oligonucleotides). The pairing properties of corresponding hybrid duplexes formed from fully complement ...
Telomerase is the ribonucleoprotein enzyme responsible for the replication of chromosome ends in most eukaryotes. In the ciliate Euplotes aediculatus, the protein p43 biochemically co-purifies with active telomerase and appears to be stoichiometric with bo ...
Telomerase, the enzyme that extends chromosomal DNA ends in most eukaryotes, contains essential RNA and protein subunits. We have been studying telomere replication in hypotrichous ciliates such as Euplotes aediculatus, which have numerous short macronucle ...
Pyranosyl-RNA ("p-RNA") is an oligonucleotide system isomeric to natural RNA and composed of the very same building blocks as RNA. Its generational, chem., and informational properties are deemed to be those of an alternative nucleic acid system that cou ...
In contrast to DNA-related research, RNA-related research is limited by the availability of synthetic sequences. Recent improvements in chem. synthesis allow Xeragon AG to offer custom RNA sequences - up to 100mers - in high quantity and quality at an affo ...
The authors evaluated the RNA binding of all eight possible stereoisomers of LNA. Synthesis of "a-l-xylo-LNA" has been accomplished and the remaining four stereoisomers, all enantiomers of the four synthesized diastereoisomers, are indirectly evaluated b ...
The reaction of d,l-5'-activated nucleotide of adenosine in the presence and absence of montmorillonite gave 60:40 and 96:4 ratios, resp. of the d,d- and l,l:d,l- and l,d-dimers. [on SciFinder (R)] ...
Replication (single-turnover) of pyranosyl-RNA (p-RNA) sequences can be accomplished reliably by template-directed ligation of 2',3'-cyclophosphates of short oligomers. The ligation process was studied using (mostly) octamers as templates and tetramers as ...
RNA binding to high-density oligonucleotide arrays has shown tantalizing differences with solution experiments. We analyze here its sequence specificity, fitting binding affinities to sequence composition in large datasets. Our results suggest that the flu ...
