34. In 1928, Frederick Griffith established there is a transforming principle in
bacterial genetics. Later on, we learn that the transforming principle is DNA
and that bacterial cells are capable of transferring genetic material from one
cell to another. Explain how this illustration shows this concept.
YOU CAN TURN BENIGN (NON-DEADLY) BACTERIA AND TRANSFORM IT INTO
LETHAL (DEADLY) BACTERIA BY GIVING IT THE DNA CODE FOR LETHAL DNA.
BASICALLY, IF YOU GIVE BACTERIA INSTRUCTIONS TO BE DEADLY, IT CAN
BECOME DEADLY.

35. Draw and label the parts of a virus: genetic material, antigen, envelope, and
capsid.
36. How does mutation increase viral diversity?
DIFFERENT DNA MAY RESULT IN NEW PROTEINS THAT PRODUCE
DIFFERENT ANTIGENS. CAN GET INTO NEW HOSTS CELLS
37. Explain in your own words how the avian flu and swine flu were able to infect
humans. Why have we not seen dog flu break-outs in humans yet?
AVIAN AND SWINE INFLUNENZA OBTAINED ANITGENS TO BIND TO HUMAN
RECEPTORS. THEY CAN ENTER HUMAN HOST CELLS FOR VIRAL
REPLICATION.
DOG FLU DOES NOT HAVE ANTIGENS TO ENTER HUMAN CELLS.
