Ribonucleic acid transcriptases in Sendai Virions and infected cells.

Transfer ribonucleic acid nucleotidyltransferase and transfer ribonucleic acid in Sendai virions.

Sendai virions contain both transfer ribonucleic acid (tRNA) nucleotidyltransferase and its substrate, tRNA missing its CCA-OH end.

Indirect evidence for the presence of Ribonucleic acid in vesicular stomatitis Virions

Mumps virus replication in chick embryo lung cells: properties of ribonucleic acids in virions and infected cells.

Ribonucleic acid (RNA) species in mumps virions and in infected cells were compared. The predominant RNA species in virions labeled with (3)H-uridine sedimented at 50S; RNA species sedimenting at 28, 18, and about 10S were also present. The virion-associated RNA species sedimenting slower than 50S contained some nucleotide sequences similar to 50S virion RNA. Although mumps virus replication wa...

Ribonucleic acid polymerase induced in cells infected with Sendai virus.

A ribonucleic acid (RNA)-dependent RNA polymerase was induced in chick embryo fibroblast cells after infection with Sendai virus (parainfluenza 1 virus). The enzyme was associated with the microsomal fraction of infected cells and reached maximum detectable activity at 18 hr after virus infection. The activity of the enzyme in vitro was dependent on the presence of added magnesium ions and all ...

Adenylate-rich sequences in Sendai virus transcripts from infected cells.

Virus-specific complementary ribonucleic acid (RNA) from cells infected with Sendai virus was isolated by a procedure involving hybridization with virion RNA and isopycnic centrifugation of the RNA hybrids. The complementary RNA contained adenylate-rich sequences which sedimented at about 4S.
