Transcription of the influenza ribonucleic acid genome by a virion polymerase. II. Nature of the in vitro polymerase product.
The properties of the ribonucleic acid (RNA) synthesized by the influenza (WSN) virion polymerase have been investigated. Most of the product RNA is synthesized in association with virion RNA species from which it can be released by heat treatment as single-stranded, ribonuclease-sensitive polynucleotides (average molecular weight, 2-hr sample, about 10(5) daltons). At least 95% of the product ...

متن کاملDeoxyribonucleic acid-dependent ribonucleic acid polymerase activity in purified trachoma elementary bodies: effect of sodium chloride on ribonucleic acid transcription.
Highly purified trachoma elementary bodies (T'ang strain), incubated in the presence of the four nucleoside triphosphates [Mg(2+), Mn(2+), 2-mercaptoethanol, tris(hydroxymethyl)aminomethane buffer (pH 7.5)] were found to incorporate (3)H-uridine triphosphate (UTP) into ribonucleic acid (RNA) molecules. Eighty-seven per cent of the labeled molecules were sensitive to ribonuclease treatment. In v...
متن کاملAzotobacter vinehndii Ribonucleic Acid Polymerase
RNA synthesis by the Azofobacter vinelandii RNA polymerase is initiated with the incorporation of a ribonucleoside triphosphate to form the 5’ terminus of the chain. The RNA chains synthesized in vifro are preferentially initiated by purine ribonucleoside triphosphates. The ratio of guanosine triphosphate to ATP termini is determined by the DNA used to direct the synthesis of RNA. When denature...
متن کاملPurification and properties of the ribonucleic acid-dependent ribonucleic acid polymerase from Halobacterium cutirubrum.
1. The RNA-dependent RNA polymerase from Halobacterium cutirubrum was purified to electrophoretic homogeneity. 2. It requires a single-stranded molecule of RNA or polyribonucleotide as template. 3. Nearest-neighbour analyses of the products formed on random poly(A,U) or alternating poly(A-U) templates and base analysis of the product of synthesis directed by wheat-germ RNA prove that the templa...
