Azotobacter vinehndii Ribonucleic Acid Polymerase III. RIBONUCLEIC ACID CI-IAI;“\; IXITIATION*

Azotobacter 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...

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

Tryptophan-transducing bacteriophages: in vitro studies with restriction endonucleases HindII + III and Escherichia coli ribonucleic acid polymerase.

The HindII + III restriction enzyme fragmentation pattern of various lambda-phi80trp deoxyribonucleic acid molecules is presented. An analysis of deoxyribonucleic acid molecules carrying deletions ending within the trp regulatory elements and a deoxyribonucleic acid molecule carrying a deletion within trpE indicates that a fragment of 8.3 X 10(5) daltons contains at least part of the trp promot...

The influence of syringomycin on ribonucleic acid synthesis.

Syringomycin, a wide-spectrum antibiotic produced by strains of Pseudomonas syringae which cause bacterial canker of peach, was able to bind to salmon sperm and calf thymus deoxyribonucleic acid but not to calf thymus histone; it also inhibited ribonucleic acid polymerase activity. These abilities to bind to deoxyribonucleic acid and to inhibit ribonucleic acid polymerase were inactivated when ...

MiR-34-a acts as a suppressor in neuroblastoma progression by targeting CD44.

OBJECTIVE To verify whether micro ribonucleic acid 34-a can exert its negative effects in human neuroblastoma cells. METHODS The study was conducted at The Affiliated Hospital of Qingdao University, Qingdao, Shandong, China during 15 months (from March 2015 to about June 2016). Quantitative reverse transcription polymerase chain reaction was used to find the differences of micro ribonucleic a...
