1. Ribonucleic acid of yeast causes the formation of a potent hemolysin in broth cultures of Streptococcus pyogenes. 2. The hemolysin whose formation is induced by yeast ribonucleic acid appears to be identical with streptolysin S. 3. Desoxyribonucleic acid, products of acid or alkaline hydrolysis of ribonucleic acid, or many other substances tested, fail to produce a similar effect. 4. Digesti...

This investigation constitutes a comparative study of the ribonucleic acid production during the course of growth at different temperatures of an obligate thermophile and a mesophile. A study of this nature aside from the quantitative data should provide information concerning the rate of ribonucleic acid production, the characteristic ribonucleic acid patterns obtained during the course of gro...

Ribonucleic acid (RNA) molecules are known to undergo conformational changes in response various environmental stimuli including temperature, pH, and ligands.

OBJECTIVE To determine the association of interferon alpha receptor-1 with success rate of interferon therapy in patients co-infected with hepatitis C virus and hepatitis B virus. METHODS The study was conducted at the Army Medical College, Rawalpindi, Pakistan, from December 2013 to November 2014, and comprised patients with hepatitis C and hepatitis B co-infection. The patients were treated...

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...

A number of trace nucleotides are reported to be present in ribonucleic acids from various sources. Cohn (I) and Davis and Allen (2) have described a nucleotide in yeast ribonucleic acids, the nucleoside of which has recently been identified as 5ribosyluracil.’ Littlefield and Dunn (3) have found small amounts of thymine, 2-methyladenine, N6-methyladenine2 (6methylaminopurine), and Ne-dimethyla...
