Griffith experiment

From his work with mice and pneumonia-causing bacteria, Frederick Griffin coined the term

• Replication
• Transcription
• Transformation
• Translation

Using the image what happened to the mice labeled X and Z?

• Both X and Z died

• Both X and Z lived

• X died and Z lived

• X lived and Z died
