The capsular polysaccharide in the heat-killed S cell extract; the polysaccharide was able to attach to R cells, thus making them virulent. C. DNA in the heat-killed S cell extract; the DNA altered the genetic makeup of R cells, allowing them to synthesize the polysaccharide capsule, thus making them virulent. D.
