چکیده

Single strand scission in duplex DNA is caused by hydroxylamine, Na-nitrite or oximes of glucose and galactose of proper low molarities. The suitable nicking in the DNA-molecule brings about the elevation of its template nature. Excessive breakage of DNA, however, reduces its template activity. The results have been discussed in relation to an effect causing cyto-differentiation and -anomalization.

Rosenkranz, Herbert S. (Columbia University, New York, N.Y.). Macromolecular synthesis and the bactericidal effect of streptomycin. J. Bacteriol. 87:606-603. 1964.-Hydroxylamine, a bacteriostatic agent which inhibits deoxyribonucleic acid (DNA), ribonucleic acid (RNA), and protein synthesis, interferes with the lethal action of streptomycin on growing cells of Escherichia coli. The addition of ...

Template requirement of maize RNA polymerase.

Maize RNA polymerase utilizes heated deoxyribonucleic acid more effectively than native deoxyribonucleic acid as a template for ribonucleic acid synthesis. A ribonucleic acid-deoxyribonucleic acid hybrid accumulates in the presence of heated deoxyribonucleic acid. The amount of product formed with either native or heat-denatured deoxyribonucleic acid does not exceed the amount of deoxyribonucle...

Lomofungin, an inhibitor of deoxyribonucleic acid-dependent ribonucleic acid polymerases.

Lomofungin, an antibiotic active against fungi, yeasts, and bacteria, was found to be a potent inhibitor of purified Escherichia coli deoxyribonucleic acid (DNA)-dependent ribonucleic acid (RNA) polymerase. It prevents RNA synthesis by a direct interaction with the polymerase and not with the template or substrate; chain elongation is halted promptly. Three DNA-dependent RNA polymerases isolate...

Effect of Helium-Neon Laser and Sodium Hypochlorite on Calf Thymus Double-Stranded Deoxyribonucleic Acid Molecule: An in Vitro Experimental Study

Introduction: Low-energy helium-neon (He-Ne) laser beam lightis used in combination with sodium hypochlorite (Na2HOCl3) for clinical purposes. Regarding this, the present study aimed to investigate the effect of He-Ne laser (632.8 nm) and sodium hypochlorite on the calf thymus double-stranded deoxyribonucleic acid (ctdsDNA) molecule.  Materials and Methods: For the purpose of the study, ctdsDNA...

Nuclear deoxyribonucleic acid-dependent ribonucleic acid polymerases from Saccharomyces cerevisiae.

Two deoxyribonucleic acid (DNA)-dependent ribonucleic acid (RNA) polymerases (I, II) have been solubilized from isolated Saccharomyces cerevisiae nuclei. The enzymes can be separated by chromatography on O-diethylaminoethyl Sephadex. Both enzymes are active with high-molecular-weight nuclear yeast DNA, although RNA polymerase I has a higher affinity for polydeoxy-adenylic-thymidylic acid and RN...
