What else can I help you with?
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?
Heat denatures the lethal pneumonia bacteria's proteins or enzymes causing them to become ineffective. Therefore, without the bacteria's proteins or enzymes functioning correctly, the lethal pneumonia bacteria die.
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 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 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
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.
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
