Griffith's Transformation Experiment - S-strain: smooth, virulent - R-strain: rough, non-virulent - heat killed S-strain: non-virulent - heat killed S-strain + R-strain: virulent - live cells could be recovered form dead mice, living R-cells "transformed" by dead S-cells Avery, MacLeod & McCarty determined that DNA is the transforming principle Hershey & Chase - used radioactive material to label DNA and protein ->infected bacteria passed on DNA - helped prove that DNA is genetic materia...

In the 1944 experiment by Avery et al., only ___ was able to transform a nonvirulent strain of bacteria into a virulent one, thereby demonstration that it is likely the ___. A) protein; chromosomal material B) genetics; protein material C) amino acid; DNA material D) DNA; genetic material D) DNA; genetic material Hershey and Chase (1952) blender experiment demonstrated that A) protein is not required for virus production B) viral coat proteins can enter the infected bacterial cells C) ...
