What was the molecule that caused transformation in Griffith's pneumonia experiment?
A molecue called the s (strain).
What results from Griffiths experiment suggested that the cause of pneumonia was not a chemical poison by the disease-causing bacteria?
To find out, he took a culture of these cells, heated the bacteria to kill them, and injected the heat-killed bacteria into the mice.
What result from griffiths experiment suggested that the cause of pneumonia was not a chemical poison released by the disease bacteria?
To find out, he took a culture of these cells, heated the bacteria to kill them, and injected the heat-killed bacteria into the mice.
What did Frederick discover?
Frederick Griffiths observed natural transformation for the first time, while he was searching for the pneumonia vaccine. He discovered that mixing a heat killed pathogenic strain of bacteria with a living nonpathogenic strain converted some cells into the pathogenic form.
The transforming factor that alters pneumonia?
The "transforming factor" that alters pneumonia bacteria was found to be DNA by the scientist Fredrick Griffiths.
What is griffith trying to accomplish by injecting mice with pneumonia causing bacteria?
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.
What did Griffith Frederick Discover?
Frederick Griffiths observed natural transformation for the first time, while he was searching for the pneumonia vaccine. He discovered that mixing a heat killed pathogenic strain of bacteria with a living nonpathogenic strain converted some cells into the pathogenic form.
Was bacterial pneumonia always fatal?
Prior to the discovery of penicillin antibiotics, bacterial pneumonia was almost always fatal
What result from Griffiths experiment suggested that the cause of pneumonia wasnt a chemical poison?
To find out, he took a culture of these cells, heated the bacteria to kill them, and injected the heat-killed bacteria into the mice. The Mice survived, suggesting that the cause of pneumonia was not a chemical poison released by the disease-causing bacteria.
This bacteriologist discovered a process called transformation by accident while preparing a vaccine against pneumonia?
Frederick Griffith
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 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".
