What is gram positive strain?
Gram-positive bacterium are those that are stained dark blue or violet by Gram Staining. This is in contrast to Gram-Negative Bacterium, which cannot retain the crystal violet stain, instead taking up the counter-stain and appearing red or pink. Gram-positive organisms are able to retain the crystal violet stain because of the high amount of peptidoglycan in the cell wall. Gram-positive cell walls typically lack the outer membrane found in Gram-negative 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 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.
Is plasmodium gram negative?
Plasmodium is not a bacteria to be classified whether gram negative or gram positive. It is a genus of parasitic protists. Infection by these organisms is known as malaria.
What happened when griffith the mice with the harmless R strain bacteria alone?
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 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
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.

The molecule that caused transformation in Griffith's mouse experiment was DNA.

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.
Is the bacterial strain in question catalase positive or negative?
The bacterial strain in question is catalase positive.
What is purple skunk?
Purple skunk is strain of marijuana, like panama red it is valued for its hight THC content and potency.
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.
