transformation
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.
transformation is the process in which one strain of bacteria is changed by a gene or genes from another strain of bacteria

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.
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.
it's called transformation!! lol
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.
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. 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 disease-causing strain of bacteria grew into smooth colonies on culture plates, whereas the harmless strain produced with rough edges.
