  1. Mit dem als Hershey-Chase-Experiment bekannt gewordenen Versuch konnte nachgewiesen werden, dass genetische Information in DNA und nicht in Proteinen codiert ist. Das Experiment wurde 1952 durchgeführt von Alfred Hershey und Martha Chase.

  2. The Hershey–Chase experiments were a series of experiments conducted in 1952 by Alfred Hershey and Martha Chase that helped to confirm that DNA is genetic material. Scientist Martha Chase and Alfred Hershey

  3. Hershey and Chase found that when bacteriophages containing 32 P (radioactive), were allowed to infect nonradioactive bacteria, all the infected cells became radioactive and, in fact, much of the radioactivity was passed on to the next generation of bacteriophages.

  4. 23. Juni 2019 · In 1951 and 1952, Alfred Hershey and Martha Chase conducted a series of experiments at the Carnegie Institute of Washington in Cold Spring Harbor, New York, that verified genes were made of deoxyribonucleic acid, or DNA.

  5. Hershey und Chase wandten bei ihren Versuchen die Methode der radioaktiven Markierung von Molekülen an. Dabei werden bestimmte Atome eines Moleküls durch radioaktiv strahlende Isotope ersetzt. Isotope. Im Chemieunterricht der Sek. I haben Sie gelernt, wie ein Atom aufgebaut ist.

  6. In their now-legendary experiments, Hershey and Chase studied bacteriophage, or viruses that attack bacteria. The phages they used were simple particles composed of protein and DNA, with the outer structures made of protein and the inner core consisting of DNA.

  7. 18. Mai 2024 · Hershey is most noted for the so-called blender experiment that he performed with Martha Chase in 1952. By showing that phage DNA is the principal component entering the host cell during infection, Hershey proved that DNA, rather than protein, is the genetic material of the phage.
