Why were the S bacteria not the R bacteria virulent?
The S bacteria are surrounded by a capsule, so it is not engulfed by the host's white blood cells. That means that it is able to proliferate and spread. The R bacteria lack the capsule (like the mutant S bacteria), so the white blood cells are able to detect and eliminate them.
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.
Why were the S bacteria but not the R bacteria virulent?
The S bacteria possess a protective polysaccharide capsule that helps them evade the immune system, allowing them to survive and cause infection. The R bacteria lack this capsule and are easily targeted and eliminated by the immune system, thus they are not virulent.
Who studied the s and r type of bacteria?
Frederick Griffith was a scientist who studied the S and R types of bacteria. He conducted experiments in the 1920s that demonstrated bacterial transformation, where genetic material can be transferred between bacterial cells. This work was foundational in understanding the concept of bacterial virulence and the basis for later research in molecular biology.
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.
Why was the mixture of S bacteria and R BACTERIA virulent?
The live R bacteria acquired a capsule and became live, virulent S 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.
Why was the mixture of heat killed s bacteria and r bacteria virulent?
The live R bacteria acquired a capsule and became live, virulent S bacteria.
What was different about the s bacteria and the r bacteria?
the conversion of R forms of one type into S forms of a different type
What was the different about the S bacteria and R bacteria?
the conversion of R forms of one type into S forms of a different type

What is the algebraic expression of 14 more than the difference of r and s?
It is |r - s| + 14 or abs(r - s) + 14.
What is the difference between humans and sharks?
questions like this make me wanna cry! h-u-m-a-n and s-h-a-r-k-s
What is the order of the linked genes r s and t if the distance between r and s is 22 mu the distance between s and t is 8 mu and the distance between r and t is 14 mu?
r-t-s
