What did hersey and chase discover?
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.
What of the three experiments gave evidence that protein was not the genetic material?
The experiment by Alfred Hershey and Martha Chase in 1952 provided evidence that protein was not the genetic material. They used bacteriophages, which are viruses that infect bacteria, and labeled the DNA with radioactive phosphorus and the protein coat with radioactive sulfur. After allowing the viruses to infect bacteria, they found that only the radioactive phosphorus (DNA) entered the bacterial cells, while the radioactive sulfur (protein) remained outside. This demonstrated that DNA, not protein, was the hereditary material responsible for passing genetic information.
What did the hershey-chase blender experiment help prove?
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.
Why are radioactive isotopes used in biology?
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.
In 1952 hershey and chase used a bacteriophageto determine that genetic material is made of what?
These two isotopes are: phosphorus-32 and sulfur-35.
What genetic material can be extracted from your body tissues and used to create a profile to identify a victim or suspect?
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.
Can you identify the part of the cell that contains genetic materials that determine traits?
what part of the cell contains genetic material or genes that determine traits
Describe the contributions of hershey and chase to the understanding that DNA is the genetic material?
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
What summarizes the findings of Hershey and Chase?
Alfred Hershey and Margaret Chase confirmed that DNA is a genetic material.
Where was the radioactive sulfur found at the end of experiment one in the hershey-chase experiment?
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.
What is putative 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).
What problems associated with the use of radioactive isotopes?
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.
