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
Why was the mixture of S bacteria and R BACTERIA virulent?
The live R bacteria acquired a capsule and became live, virulent S 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 is the difference between r and s bacteria?
r is rough bacteria and s is smooth bacteria. smooth bacteria causes disease and makes a thick outer capsule.
Why were the S bacteria but not the R bacteria virulent?

Who studied the s and r type of bacteria?
Griffith
What is the name of the process that was involved in changing griffith's r bacteria to s bacteria?
Transformation
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.
Which type of bacteria caused disease the S form or R form?
s form
What effect did an injection of live R bacteria mixed with heat killed S bacteria have on the mice?
The mice injected with mixture died
The s strain and the r strain of S pneumoniae are different in that?
The S strain produces a capsule but the R strain does not
What did Griffith find to be true after his experiments with the s and r strain of bacteria?
Griffith hypothesized that a chemical component from the virulent S cells had somehow transformed the R cells into the more virulent S form.
