Abortive transcription products of vaccinia virus are guanylylated, methylated, and polyadenylylated.

Abortive transcription products were synthesized in vitro by UV-irradiated vaccinia virus particles that were incubated with all four ribonucleoside triphosphates or by unirradiated particles that were incubated in reaction mixtures deficient in CTP or UTP. The RNA sedimented at 4 to 6S in sucrose gradients, suggesting that premature termination had occurred, presumably in one case because the ...

Folding RNA/DNA hybrid duplexes

MOTIVATION While there are numerous programs that can predict RNA or DNA secondary structures, a program that predicts RNA/DNA hetero-dimers is still missing. The lack of easy to use tools for predicting their structure may be in part responsible for the small number of reports of biologically relevant RNA/DNA hetero-dimers. RESULTS We present here an extension to the widely used ViennaRNA Pa...

Structural Aspects of the Antiparallel and Parallel Duplexes Formed by DNA, 2’-O-Methyl RNA and RNA Oligonucleotides

This study investigated the influence of the nature of oligonucleotides on the abilities to form antiparallel and parallel duplexes. Base pairing of homopurine DNA, 2'-O-MeRNA and RNA oligonucleotides with respective homopyrimidine DNA, 2'-O-MeRNA and RNA as well as chimeric oligonucleotides containing LNA resulted in the formation of 18 various duplexes. UV melting, circular dichroism and fluo...

ASSOCIATED (SEMI)HYPERGROUPS FROM DUPLEXES

In this paper using strongly duplexes we introduce a new class of (semi)hypergroups. The associated (semi)hypergroup from a strongly duplex is called duplex (semi)hypergroup. Two computer programs written in MATLAB show that the two groups $Z_{2n}$ and $Z_{n}times Z_{2}$ produce a strongly duplex and its associated hypergroup is a complementary feasible hypergroup.

Newcastle disease virus-specific RNA: polyacrylamide gel analysis of single-stranded RNA and hybrid duplexes.

Newcastle disease virus-specific [(3)H]uridine-labeled 18S RNA was resolved by polyacrylamide gel electrophoresis into several components with molecular weights from 450,000 to 840,000. The analysis of 35 and 24S virus-specific RNA also revealed several components in each sedimentational class. The conversion of 18S RNA into double-stranded form by hybridization with an excess of unlabeled viri...
