What was the result of Hershey and Chase's experiments regarding the transfer of genetic material from the virus to the bacteria?
Options
- AProteins entered the bacteria from the viruses
- BRNA entered the bacteria from the viruses
- CDNA entered the bacteria from the viruses
- DNeither proteins nor DNA entered the bacteria from the viruses
Correct answer
C. DNA entered the bacteria from the viruses
Step-by-step solution
Similarly, viruses grown on radioactive sulfur contained radioactive protein but not radioactive DNA because DNA does not contain sulfur. Radioactive phages were allowed to attach to E. coli bacteria. Then, as the infection proceeded, the viral coats were removed from the bacteria by agitating them in a blender. The virus particles were separated from the bacteria by spinning them in a centrifuge. Bacteria which were infected with viruses that had radioactive DNA were radioactive , indicating that DNA was the mater
