What is the process in which one strain of bacteria appears to change into another?
Boobs
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.
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
Which type of strain permanently changes rocks?
Plastic strain, which occurs under high temperatures and pressures, can permanently change rocks by causing them to deform without breaking. This type of strain can lead to the development of new minerals and structures within the rock.
What is the process in which one strain of bacteria changes into another?
transformation
Strain of bacteria?
s-strain bacteria make
What important question remained unanswered by griffith experiment?
Assuming you mean the Frederick Griffith bacterial experiment, the question left unanswered was how the rough strain (less harmful) bacteria transformed into the smooth strain (lethal) bacteria. When he injected live rough strain bacteria, the mouse lived. When he injected live smooth strain bacteria, the mouse died. But if dead smooth strain bacteria was injected, the mouse lived. So if either live rough strain or dead smooth strain could be injected without killing the mouse, then it would stand to reason that one could inject both, the mouse should live. But the mouse died. So he figured the rough strain was somehow taking on the characteristics of the smooth strain bacteria, perhaps by being in close proximity to dead smooth strain bacteria, but he didn't know why. We now know that the smooth strain DNA was somehow getting grafted into the rough strain bacteria and making it able to create a coating which prevented the immune system (of the mouse in this case) from killing it. In case you mean the John Howard Griffin racial change experiment, the question left unanswered was how to stop racism. While his experiment was not completely successful, he gained a number of insights into the experiences of men of color in America. He was able to speak to people in both groups, but yet, he was not able at that point to get them to reconcile with each other.
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 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.
What is an effector strain of bacteria?
An effector strain of bacteria is a strain that has the ability to produce and secrete specific proteins or molecules called effectors, which can manipulate host cells or immune responses to benefit the bacterium. These effectors can help the bacterium evade host defenses, establish infection, and promote survival within the host.
