Griffith was trying to show the transformation of DNA in his experiment where DNA was transfered enabling the viable cell of bacteria to non- viable.

Fred Griffith worked with what type of bacteria?
He worked with pneumococci, the bacteria that causes pneumonia.
Explain how the bacteria in griffith's experiment were transformed?
The harmless living bacteria took in pneumonia-causing DNA(genes) from the heat-killed, pneumonia-causing bacteria, as a result of which the harmless bacteria changed into bacteria that cause pneumonia.
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 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".
Why do you think heating the lethal pneumonia bacteria in Griffith's experiment killed them?
Heating the lethal pneumonia bacteria in Griffith's experiment likely killed them because the high temperature denatured the proteins and disrupted the structure of the bacterial cells, leading to their death. This process would have rendered the bacteria unable to replicate or cause infection in experimental animals.
What was the molecule that caused transformation in Griffith's pneumonia experiment?
The molecule that caused transformation in Griffith's pneumonia experiment was DNA. Specifically, it was the transfer of DNA from heat-killed virulent bacteria to live non-virulent bacteria that resulted in the transformation of the non-virulent bacteria into a virulent form.
What happened when Griffith injected mice with a mixture of heat-killed pneumonia-causing bacteria and live bacteria of the harmless type?
that it was very gay
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".
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
Which new phenomenon did Griffith focus on during his work with pneumonia-causing bacteria and mice?
transfer of genetic material through transformation
Which new phenomenon did Griffith focus on during his work with pneumonia causing bacteria and mice?
transfer of genetic material through transformation
How did Frederick Griffith demonstrate that DNA not protein could cause changes in a cell's genotype?
Frederick Griffith demonstrated that DNA, not protein, could cause changes in a cell's genotype through his experiment with Streptococcus pneumoniae bacteria. He observed that injecting mice with a mixture of non-virulent and heat-killed virulent strains resulted in the transformation of the non-virulent bacteria into a virulent form. This indicated that the genetic material responsible for the transformation was DNA.
