In 1928, __________ was surprised to find that when he killed pathogenic bacteria, then mixed the bacterial remains with living harmless bacteria, some living bacterial cells became pathogenic. Frederick Griffith In 1952, ___________ used bacteriophages to show that DNA is the genetic material of T2, a virus that infects the bacterium Escherichia coli (E. coli). Hershey-Chase __________ are viruses that infect bacterial cells. Bacteriophages ______ discovered the relationships between D...

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...

GCD Group Problems Test with Complete Solutions 1. From their experiments, Hershey and Chase concluded that the genetic material of T2 is DNA. Were there data consistent with the genetic material being RNA? If so, how could they have experimentally distinguished between DNA and RNA as the genetic material? You can assume that they had all types of radiolabeled bases (A, T, G, C and U) at their disposal. - Answer-Hershey and Chase used 32P, a radioisotope of phosphorus, to label DNA in T2 Phag...
