Multiple Choice

The DNA of a phage was injected into the bacterial host, but the protein coat remained outside. The viral DNA directed the host to replicate the new phage viruses. Which scientist(s) are associated with this finding?

Hershey and Chase.

Meselson and Stahl.

Thomas and Walters.

Watson and Crick.

Chargaff.

Verified step by step guidance

Understand the context of the problem: The problem describes an experiment where viral DNA is injected into a bacterial host, leading to the replication of new viruses, while the protein coat remains outside.

Identify the key experiment: This description matches the famous experiment that demonstrated that DNA is the genetic material, not protein.

Recall the scientists involved: The experiment described is known as the Hershey-Chase experiment.

Review the Hershey-Chase experiment: Alfred Hershey and Martha Chase used bacteriophages (viruses that infect bacteria) to show that DNA, not protein, is the material that carries genetic information.

Conclude with the correct association: Based on the description and historical context, the scientists associated with this finding are Hershey and Chase.
