What else can I help you with?
Hershey and chase concluded that the genetic material of the bacteriophage was?
DNA. Hershey and Chase conducted the blender experiment using bacteriophages to show that DNA, not protein, is the genetic material that is passed on during viral infection.
What did Hershey and chase attach radioactive sulfur to?
Hershey and Chase attached radioactive sulfur to proteins in the bacteriophage's outer coat in one experiment, and to DNA in another experiment, to determine which molecule was injected into the host bacteria during viral infection. They found that only DNA, not proteins, was passed on to the host bacterium. This confirmed that DNA is the genetic material responsible for heredity.
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 was Alfred Hershey and Martha Chase's experiment so important?
Hershey and Chase's experiment using bacteriophages proved that DNA, not protein, is the genetic material in cells. This discovery was a key milestone in understanding how genetic information is passed from one generation to the next. It laid the foundation for the field of molecular biology.
Who determined DNA was a chemical that contained inherited information?
The assumption of inheritence material was first suggested by Griffith's experiments on diplococcus. Later on in 1944 three scientist; Avery, Macleod, and Mc. Carty repeated the Griffith's experiment and finally Harshey and Chase perform the experiment with bacteriophage and E.coli and prooved that DNA is a genetic material.
The bacteriophage used by Hershey and chase consisted of 2 types of molecules?
DNA and protein
What used by hershey and chase in their experiments?
Bacteriophage
What was used by Hershey and chase in their experiment?
Bacteriophage
Who concluded that the genetis material of a bacteriophage is DNA?
The scientists Alfred Hershey and Martha Chase conducted a series of experiments at the Carnegie Institute of Washington in 1952, and concluded that the genetic material of a bacteriophage was DNA.
Why did Alfred Hershey and Martha Chase chose bacteriophage as their virus?
Because it infects bacteria and uses it as a factory to replicate and create more bacteriophage. T2 Bacteriophage undergoes lytic life cycle and NOT lysogenic life cycle
What result did Hershey and chase observe?
they concluded that the genetic material of the bacteriophage was DNA, not protein
What did Hershey and Chase's work establish?
Hershey and Chase completed research proving that DNA is the "stuff of heredity" and not just protein in 1952. There is information on how they used a bacteriophage to prove this residing on the Answers site.
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
Hershey and chase concluded that the genetic material of the bacteriophage was?
DNA. Hershey and Chase conducted the blender experiment using bacteriophages to show that DNA, not protein, is the genetic material that is passed on during viral infection.
What is the control group in the hershy-chase experiment?
The control group in the Hershey-Chase experiment was the group of bacteriophages that were not subjected to any treatment. They were used as a baseline to compare against the experimental group that was treated with radioactive markers to track the transmission of genetic material.
What did Hershey and Chase show the genetic material of the t2 bacteriophage was?
DNA is the genetic material. However, Hershey-Chase also stated that some little sulfur containing material also entered the bacterial cell. Looking at these two conclusions, Hershey-Chase could not reach a definite conclusion as to whether DNA or Protein contains the genetic material. The conclusion came from Watson-Crick who stated that the sulfur containing material could have entered the cell due to the fact that DNA replication and subsequently translation of the mRNA leads to the synthesis of sulfur containing protein which were found in the bacterial cell.
What scientific hypotheses can be tested by a pulse-chase experiment?
Movement of molecules through a cell over time
