How did hershey and chase label phage protein
WebHershey and Chase designed a very simple experiment to determine which molecule, DNA or protein, acted as the genetic material in phages. To do this, they made use of a technique called radioactive labeling. WebThe phage infects a bacterium by attaching to it and injecting its genetic material into it. They put labels on phage DNA with radioactive Phosphorus-32. They then followed the phages while they infected E. coli. Hershey and Chase concluded that DNA, not protein, was the genetic material.

WebThe most widely cited application of this kind is the Hershey–Chase experiment, in which phosphorus-32 was used to label the phage DNA and sulfur-35 to label the phage protein.4Subsequent infection with each type of labeled phage showed that only the phosphorus-32-labeled nucleic acid component of the virus entered the bacterial cell to a … Web11 de abr. de 2024 · An E. coli strain that contained wild-type versions of both genes was infected with P1 phage, and then a P1 lysate was obtained.
