"A Biochemical Mechanism for the Production of Abnormal Tetrad Ratios." Offprint from: Separatum Experientia, 17, 175, 1961.

[No place:: no publisher], 1961., 1961. 8vo. 5 pp. Figs. Printed wrappers. Ownership rubber stamp of Norman Horowitz, California Institute of Technology. Fine. Hydrolytic deamination of the purine bases is a possible explanation for the observed mutation. This can be achieved in vitro by HNO2 or by ultraviolet light in the presence of alkali. The resulting hydroxy-purine bases can be reanimated by ammonia in the presence of amino-purine bases. A theory to explain the observed phenomenon is proposed and genetic consequences are discussed.
