1. Griffith's experiments with heat killed pathogenic bacteria and live non-pathogenic bacteria indicated something from the dead bacteria could do something to the living, non-pathogenic bacteria that he called transfor- mation. What changes were observed in colony appearance and pathogenic- ity?: When the heat-killed S cells were mixed with the living R cells they combined and formed living S cells- smooth encapsulated cells 2. What biological macromolecule did Avery, McCarty, and MacLeod i...
