The Effects of 3'-deoxyadenosine on the Synthesis of Ribonucleic Acid.

Synthesis of deoxyribonucleic acid, ribonucleic acid, and protein during sporulation of Clostridium perfringens.

The kinetics of deoxyribonucleic acid (DNA), ribonucleic acid (RNA), and protein synthesis as well as protein breakdown during sporulation by Clostridium perfringens were determined. Maximum levels of DNA and net RNA synthesis occurred 3 and 2 h, respectively, after inoculation of sporulation medium. The rate of RNA synthesis decreased as sporulation progressed. Deoxyadenosine increased uptake ...

Long-term incorporation of tritiated adenine into deoxyribonucleic acid and ribonucleic acid by Treponema pallidum (Nichols strain).

Treponema pallidum (Nichols strain), extracted in medium containing Eagle minimal essential medium 50% fresh, heat-inactivated normal rabbit serum, and 1.0 mM dithiothreitol, was incubated under 3% oxygen in the presence of tritiated nucleic acid precursors. [8-3H]adenine was incorporated with high efficiency into trichloroacetic acid-insoluble material; 2'-deoxyadenosine and uridine were incor...

Covalent linkage between ribonucleic Acid primer and deoxyribonucleic Acid product of the avian myeloblastosis virus deoxyribonucleic Acid polymerase.

Initiation of deoxyribonucleic acid (DNA) synthesis by the avian myeloblastosis virus DNA polymerase was previously suggested to involve a ribonucleic acid (RNA) primer, the initial product being a DNA molecule joined by a phosphodiester bond to the RNA primer. The existence and nature of such an RNA-DNA joint was investigated by assaying for transfer of a (32)P atom from an alpha-(32)P-deoxyri...

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

Synthesis and coating of nanosilver by vanillic acid and its effects on Dunaliella salina Teod.

Plant phenolics have high reducing capacity which can be exploited in the synthesis of nanomaterials. In the present study, phytoreductant vanillic acid is used to produce and coat silver nanoparticles. The effects of Ag nanoparticles on the unicellular green algae D. Salina were then investigated. Under optimum  pH and temperature, silver ions were reduced to silver metal by vanillic acid. The...
