What did Hershey and Chase use to radioactively label the T2 phage’s proteins? Here is the answer to Hershey and Chase used _____ to radioactively label the T2 phage’s proteins.
Hershey and Chase used _____ to radioactively label the T2 phage’s proteins.
- Below are the answer and explanations.
Hershey and Chase Experiment
Hershey and Chase Experiment, an experiment by Alfred Hershey and Martha Chase in 1952 using T2 phage to prove that the genetic material of phage is DNA.
A.D. Herskey and M. Chase in 1952 used T2 phage to prove that the genetic material of phage was DNA. The DNA of the phage was first labeled with 32P and the protein of the phage was labeled with 35S, and the phage was adsorbed onto the E. coli. Then the two were separated by a tissue masher. It was found that almost all of the 35S radioactivity could be pulled off the cell, while most of the 32P was injected into the cell. The phage proliferated normally in the cell.
In contrast, more than half of the 32P was found in the DNA of the later phage. It is clear that the phage DNA brings new information into the cell. This information specifies all the conditions necessary for the phage to proliferate in the cell, thus producing offspring phages that are genetically identical to the parent phage.
This experiment demonstrates that the DNA of phage is the material that determines heritability.
