To discover the identity of the transforming principle, Avery and his associates ruptured heat-killed, encapsulated cells to release their contents. RNA, DNA, protein, and purified polysaccharide coats were isolated and were tested for transforming activity. Avery and his associates found that only R cells mixed with purified DNA isolated from dead S cells were transformed to S cells. When R cells were mixed with purified RNA, with the polysaccharide coat, or with protein extracted from dead S cells, only R cell colonies were isolated. Do these results support their hypothesis? Explain.
