This sounds like a variation of the Hershey-Chase experiment.
. The Hershey-Chase experiment proved DNA is genetic material by using the isotopic marker ³²P which labels DNA. In 1952 an elegant experiment by Alfred Hershey and Martha Chase confirmed DNA as the genetic material. We know about Griffiths experiment and experiments that followed to discover the hereditary material in organisms.
But it was not accepted by all until Hershey and Chase published their experimental. For the first few seconds the Skittles were able to withstand a full force flame but after about 5 seconds some distortion was observed in the most heavily immolated of the Skittles. Induction of Transformation by a Desoxyribonucleic Acid Fraction Isolated.
The AveryMacLeodMcCarty experiment was an experimental demonstration reported in 1944 by Oswald Avery Colin MacLeod and Maclyn McCarty that DNA is the substance that causes bacterial transformation in an era when it had been widely believed that it was proteins that served the function of carrying genetic information with the very word protein itself coined to. The results of the experiment supported the theory that DNA is the genetic material. Como resultado de estos resultados incontrovertibles los científicos que habían criticado el experimento de Avery MacLeod y McCarty se convencieron del papel biológico muy importante del ADN.
Avery MacLeod and McCarty 1944. The achievement by the. Studies on the Chemical Nature of the Substance Inducing Transformation of Pneumococcal Types.
El experimento de Alfred D. No DNA and RNA are both considered to be the genetic material but due to more stability of DNA it is preferred for the storage of genetic information. Is DNA the only genetic material.
