t He then took the R strain (rough strain) and injected it into the mice and found that they did not contract the pneumonia illness and survived the insertion of the strain
What else can I help you with?
What effect did an injection of dead S bacteria have on the mice griffith studied?
The injection of dead S bacteria by Griffith resulted in no harmful effects on the mice. However, when the live R strain was injected along with the dead S bacteria, it caused the mice to become sick and die. This experiment demonstrated that the genetic material from the dead S strain could transform the harmless R strain into a deadly one.
What did Fred Griffith discover when he injected mice with a mixture of dead pathogenic S cells and living harmless r cells of Streptococcus pneumonia?
Fred Griffith discovered that the harmless R strain of Streptococcus pneumoniae could be transformed into the deadly S strain when mixed with heat-killed S strain bacteria. This experiment provided evidence for the concept of bacterial transformation, where genetic material can be transferred between different strains of bacteria.
What did fred griffith find to be true after his experiment with the S and R strains of bacteria?
Fred Griffith found that genetic information could be transferred between different strains of bacteria, specifically between the harmless R strain and the virulent S strain of bacteria. This led to the discovery of transformation, a process where genetic material is exchanged between bacteria.
What is the molecule that caused transformation in Griffith's mouse experiment?
The molecule that caused transformation in Griffith's mouse experiment was DNA. When heat-killed S strain bacteria (which had DNA) were mixed with live R strain bacteria (which did not), the DNA from the dead S strain bacteria was able to transfer genetic information to the live R strain bacteria, making them pathogenic.
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.
Who Was responsible for the experiment with mice and bacteria that led to the hypothesis that when two bacteria were mixed together something was passed to the living cells?
This experiment was conducted by Frederick Griffith in 1928. He observed that when he mixed a harmless strain of bacteria with a heat-killed virulent strain, the harmless bacteria were transformed into a virulent form. This led to the hypothesis that something in the heat-killed bacteria had transformed the live bacteria.

What did Griffth observe when he injected a mixture of heat killed disease causing bacteria and live harmless bacteria into mice?
Griffith discovered that the mice still died, indicating that the harmless bacteria had been transformed into disease-causing bacteria by a hereditary factor from the heat-killed bacteria. This experiment laid the foundation for the discovery of bacterial transformation by Avery, MacLeod, and McCarty.
When Fredrick griffith injected mice with a mixture of both heat killed smooth strain bacteria and live rough strain bacteria an unexpected result occured this result was?
The unexpected result was that the previously harmless rough strain bacteria were able to take up genetic material from the heat-killed smooth strain bacteria, becoming virulent. This demonstrated the concept of bacterial transformation and laid the foundation for understanding DNA as the genetic material.
What is the molecule that caused transformation in Griffith's mouse experiment?
The molecule that caused transformation in Griffith's mouse experiment was DNA. When heat-killed S strain bacteria (which had DNA) were mixed with live R strain bacteria (which did not), the DNA from the dead S strain bacteria was able to transfer genetic information to the live R strain bacteria, making them pathogenic.
The strain of bacteria that caused pneumonia grew into what colonies on culture plates?
The disease-causing strain of bacteria grew into smooth colonies on culture plates, whereas the harmless strain produced with rough edges.
What is the name of the process that was involved in changing griffith's r bacteria to s bacteria?
The process is called transformation, and it was the first direct evidence that genetic information could be transferred between bacteria. In Griffith's experiment, the heat-killed S strain released its genetic material, which was then taken up by the live R strain, converting it into the deadly S strain.
What was 'transformed' in Griffith's experiment?
In Griffith's experiment, non-pathogenic bacteria were transformed into pathogenic bacteria by being exposed to heat-killed pathogenic bacteria, a process now known as transformation. This led to the discovery of genetic material transfer between bacteria.
Who discovered that the hereditary system of one strain of bacteria?
Frederick Griffith was a British bacteriologist. He discovered that hereditary system of one strain of bacteraia. His experiment showed how bacteria changed its form and function. It is called Griffith's experiment which he carried out in 1928
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
