The process by which one strain of bacteria is apparently changed into another strain is called what?
The process by which one strain of bacteria is apparently changed into another strain is called bacterial transformation. This process involves the uptake and expression of foreign DNA by bacteria, leading to genetic changes.
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.
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.
Cells that carry out a response to a stimulus are called?
effector
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.
Strain of bacteria?
s-strain bacteria make
What is transformation in DNA?
transformation is the process in which one strain of bacteria is changed by a gene or genes from another strain of 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.
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 transformed from rough strain bacteria to smooth strain cells?
The process of transforming rough strain bacteria into smooth strain cells involves transferring genetic material - specifically a capsule gene - from a smooth strain to the rough strain. This genetic transfer results in the expression of a protective capsule on the surface of the rough strain cells, converting them into smooth strain cells with enhanced virulence.
How did oswlad Avery identify the molecule that transformed the R strain of bacteria into the S strain?
Oswald Avery identified the transforming molecule by conducting a series of experiments using heat-killed S strain bacteria and live R strain bacteria. He systematically purified the components of the heat-killed S strain and tested each one for its ability to transform R strain bacteria into the virulent S strain. Avery found that only the DNA from the S strain could induce the transformation, leading him to conclude that DNA is the hereditary material responsible for this transformation. His work provided crucial evidence for the role of DNA in genetics.
What is measles bacteria or virus?
Measles is an infection of the respiratory tract that can be caused by both a bacteria and a virus. Most people think of the virus strain typically, as there is a vaccine for it, and people rarely need to be treated with antibiotics for the bacteria strain.
What do the terms strepto mean?
Its referring to a specific strain of bacteria.
When a strain of bacteria is permanently change into another?
Nobody knows
What is the process in which one strain of bacteria changes into another?
transformation
