Everything is good so far. Let's make sure Griffith is on track...
Silence, dog! I must concentrate. I'm experimenting with 2 different strains of streptococcus pneumoniac. Based on my data, it appears the rough strain is virulent while the smooth strain is non-virulent.
So you've discovered that genetic information can be transferred between cells?
Haha! Yes, yes! I'm a genius. I shall name this process transformation.

Is that... a talking dog? Anyways... We've discovered that DNA is responsible for the development of pneumonia in mice infected with the heat-killed S and live R-strain bacteria. Transformation did not occur when DNA is cut up which means it is not protein but rather DNA which contains genetic information.
Well if it isn't Avery, MacLeod, and McCarty! How is your experiment going?

We're conducting an experiment using radioactive substances and bacteriophages (aka viruses that infect DNA)! We've discovered that the genetic material of the bacteriophage is a nucleic acid (DNA).
Okay... Halfway done. Let's see what Hershey and Chase are up to.
