Hershey and chase
Hershey and Chase's experiments in 1952 provided evidence that DNA, not protein, is the genetic material in bacteriophages. They used radioactive isotopes to track the transmission of DNA and protein from the phage to the bacteria during infection, showing that it was the DNA that carried the genetic information.
The Hershey-Chase blender experiment helped prove that DNA, not protein, is the genetic material of a bacteriophage. By using radioactive labeling, they were able to track the transmission of genetic material from the virus to the infected bacteria, showing that it was the DNA and not the protein coat that carried the genetic information.
It has a myriad of uses such as for diagnostic imaging purposes, treatment of cancerous tumors and for molecular biology research such as causing a specific genetic mutation in plants.
Any cell from your body, which have the nucleus, will do for genetic material. So you can collect the blood, which have white blood cells, will do. Biopsy from any part gives you enough cells for the genetic material, you need for genetic testing.
These two isotopes are: phosphorus-32 and sulfur-35.
what part of the cell contains genetic material or genes that determine traits
Hershey and Chase radioactively labelled T2 bacteriophage with P (DNA) and S (protein) to determine if protein or DNA carried the genetic material. They let the bacteriophage infect E.coli. The radioactive material found in the host E.coli contained the radioactive P (found in DNA) as the bacteriophage had multiplied inside the cell, but the radioactive S was not found inside the cell. Therefore DNA is the hereditary molecule resorce - some other guy off the internet
Alfred Hershey and Margaret Chase confirmed that DNA is a genetic material.
At the end of Experiment One in the Hershey-Chase experiment, radioactive sulfur, which labeled the protein coats of the T2 bacteriophage, was found in the supernatant, indicating that the protein did not enter the bacterial cells. This suggested that proteins were not the genetic material responsible for transferring traits to the bacteria. In contrast, the radioactive phosphorus used to label DNA was found in the bacterial cells, supporting the conclusion that DNA is the genetic material.
Putative genetic material is a segment of DNA whose protein and function is not known, but it is believed to be a gene based on its open reading frame (part of the reading frame that contains no stop codons).
The hazards of radioactive materials are basically three:radiation burns and hair loss from intense radiationcancer from long term low level exposure to radiation or from intense, short-term exposurepotential for genetic damage - demonstrated in test animals but not seen in humans such as survivors of the bombings of Hiroshima and Nagasaki.
The genetic material is in the nucleus to protect it.
