Griffith Avery and Hershey and Chase

Who worked with a "new" technology called radioactive labelling?

• Watson & Crick

• Hersey & Chase

• Griffith

• Avery, MacLeod, & McCarthy

This scientist discovered that DNA was the transforming principal by destroying different parts of the bacteria until a mouse lived and the R strain didn't transform into S.

• Miescher

• Griffith

• Avery

• Chargaff

Who discovered that bacteria could be changed by the process of transformation?

• Griffith

• Hershey & Chase

• Avery

• Franklin

Who demonstrated that DNA is the genetic material using bacteriophages?

• Griffith

• Avery

• Hershey & Chase

• Watson & Crick

Which experiment involved the use of radioactive sulfur and phosphorus to trace protein and DNA?

• Griffith's experiment

• Avery's experiment

• Hershey-Chase experiment

• Mendel's experiment

What was the main conclusion of Griffith's experiment with Streptococcus pneumoniae?

• DNA is the genetic material

• Proteins are the genetic material

• Bacteria can transform

• Viruses can infect bacteria

Which scientist(s) used enzymes to demonstrate that DNA is the transforming principle?

• Griffith

• Avery, MacLeod, & McCarty

• Hershey & Chase

• Watson & Crick

What did Hershey and Chase use to label DNA in their experiments?

• Radioactive sulfur

• Radioactive phosphorus

• Radioactive carbon

• Radioactive nitrogen

In Griffith's experiment, what was the result when heat-killed S strain was mixed with live R strain?
