Question 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 transformation. What changes were observed in
colony appearance and pathogenicity?
CORRECT ANSWER
When the heat-killed S cells were mixed with the living R cells they combined and formed
living S cells- smooth encapsulated cells
Question 2
What biological macromolecule did Avery, McCarty, and MacLeod identify as Griffith's
transforming factor
CORRECT ANSWER
DNA
Question 3
Chromatin is composed of protein and DNA. Likewise bacterial viruses (bacteriophage) are
composed of DNA and protein. In the Hershey and Chase experiments which of these two
molecules entered the bacterial cell and which stayed on the outside?
CORRECT ANSWER
S-protein stays outside cells
P-DNA enters cells
