How did Griffith experiments prove DNA is responsible for mice developing pneumonia?
Griffith's experiments involved injecting mice with different strains of Streptococcus pneumoniae. He observed that mice injected with the heat-killed virulent strain survived, while those injected with live non-virulent strains did not. Remarkably, when he mixed heat-killed virulent bacteria with live non-virulent bacteria, the mice developed pneumonia and died. This indicated that some "transforming principle" from the dead virulent bacteria was taken up by the live non-virulent bacteria, suggesting that DNA was responsible for the trait of virulence.
What else can I help you with?
What important question remained unanswered by Frederick Griffith's experiments with rats?
Frederick Griffith's experiments showed that genetic material could be transferred between bacteria, but the exact nature of this material remained unclear. Specifically, it was unknown if the genetic material was protein-based or DNA-based. This question was later resolved through the work of Avery, MacLeod, and McCarty, who demonstrated that DNA was the genetic material responsible for the transformation observed by Griffith.
What did Avery's experiments add to the knowledge gained from Griffith's experiments?
American biologist Oswald Avery and his colleagues took Griffith's experiments one step further. To test whether protein was the transforming factor, they treated Griffith's mixture of heat-treated deadly strain and live harmless strain with protein-destroying enzymes. The bacterial colonies grown from the mixture were still transformed. Avery and his colleagues concluded that protein could not be the transforming factor.
What is the order of experiments proving that DNA is the genetic material is?
griffith's experiment
The scientists responsible for the discovery of bacterial transformation is?
The scientists responsible for the discovery of bacterial transformation are Oswald Avery, Colin MacLeod, and Maclyn McCarty. They demonstrated that DNA is the genetic material that carries hereditary information in bacteria.
Which are the three experiments gave evidence that protein was not the genetic material?
Griffith, Avery, Hershey, and Chase
What result from griffith's experiments suggested that the cause of pneumonia was not a chemical poison released by the disease-causing bacteria?
The difference between "walking pneumonia" and "true pneumonia".
During his experiments to find a cure for pneumonia Frederick Griffith discovered that one strain of bacteria had been transformed into another Griffith called this process?
it's called transformation!! lol
Oswald Avery and his colleagues showed that the transforming agent in Griffith's experiments was?
DNA. Oswald Avery and his colleagues demonstrated that the transforming agent responsible for the bacterial transformation in Griffith's experiments was DNA, not protein as previously thought. Their work laid the foundation for understanding the role of DNA in heredity.

What term describe a concept discovered by scientist Frederick griffith?
The term that describes the concept discovered by scientist Frederick Griffith is "transformation." Griffith's experiments with pneumonia-causing bacteria in mice led to the discovery that genetic material can be transferred between different bacterial strains, causing one strain to inherit traits from the other. This laid the groundwork for understanding the process of genetic transformation.
What did Frederick Griffith what to learn about bacteria?
Griffith wanted to learn how certain types of bacteria produce a serious lung disease know as pneumonia.

What hypothesis did griffith from the results of his experiments?
Griffith thought that genetic information was passed along by proteins.http://wiki.answers.com/What_hypothesis_did_griffith_form_from_the_result_of_his_experiment#ixzz15y0eyO5L
Fred Griffith worked with what type of bacteria?
He worked with pneumococci, the bacteria that causes pneumonia.
What result from Griffith experiment suggested that the cause of pneumonia was not a chemical poison released by the diseases causing bacteria?
The difference between "walking pneumonia" and "true pneumonia".
What is the order of experiments proving that DNA is the genetic material is?
griffith's experiment
How do you Summarize griffith's transformation experiments?
Frederick Griffith introduced the Griffith experiment in 1928. This experiment proved that bacteria can carry genetic information through a process called transformation.
