The scientists Alfred Hershey and Martha Chase conducted a series of experiments at the Carnegie Institute of Washington in 1952, and concluded that the genetic material of a bacteriophage was DNA.
Hershey and Chase radioactively labelled T2 bacteriophage with P (DNA) and S (protein) to determine if protein or DNA carried the genetic material. They let the bacteriophage infect E.coli. The radioactive material found in the host E.coli contained the radioactive P (found in DNA) as the bacteriophage had multiplied inside the cell, but the radioactive S was not found inside the cell. Therefore DNA is the hereditary molecule resorce - some other guy off the internet
Transduction is the type of sexual exchange among bacteria in which DNA is carried into a bacterial cell by means of a bacteriophage virus. The bacteriophage acts as a carrier of genetic material, facilitating the transfer of DNA from one bacterium to another during the infection process.
a key unlocks a door. The genetic material of a bacteriophage enters a bacterium by attaching to the bacterial cell wall and injecting its DNA or RNA into the host cell, taking over the cell's machinery to replicate itself. Just like a key unlocks a door to gain entry, the bacteriophage's genetic material gains entry into the bacterium to begin infection.
DNA is the genetic material. However, Hershey-Chase also stated that some little sulfur containing material also entered the bacterial cell. Looking at these two conclusions, Hershey-Chase could not reach a definite conclusion as to whether DNA or Protein contains the genetic material. The conclusion came from Watson-Crick who stated that the sulfur containing material could have entered the cell due to the fact that DNA replication and subsequently translation of the mRNA leads to the synthesis of sulfur containing protein which were found in the bacterial cell.
Correct. For APEX it is, A protective shell around a virus.
they concluded that the genetic material of the bacteriophage was DNA, not protein
DNA. Hershey and Chase conducted the blender experiment using bacteriophages to show that DNA, not protein, is the genetic material that is passed on during viral infection.
T4 bacteriophage is a DNA virus. It infects bacteria by injecting its DNA into the host cell and hijacking the cell's machinery to replicate its genetic material.

A bacteriophage ("eater of bacteria") inject their DNA (or RNA) into the cell.
We can insert about 5-25 kb sized foreign DNA in a lambda bacteriophage vector.

The Hershey-Chase blender experiment helped prove that DNA, not protein, is the genetic material of a bacteriophage. By using radioactive labeling, they were able to track the transmission of genetic material from the virus to the infected bacteria, showing that it was the DNA and not the protein coat that carried the genetic information.
Hershey and Chase's experiment used bacteriophage T2, which consists of protein and DNA molecules. They were able to show that only the DNA component of the bacteriophage was responsible for carrying genetic information into the host bacterial cell during infection.
