In 1952 who showed that DNA is the genetic material of the T2 phage?
Hershey and Chase did a series of classic experiments demonstrating that DNA is the genetic material of the T2 phage.
When a T2 bacteriophage infects an E. coli cell what part of the phage enters the bacterial cytoplasm?
the whole phage
What did Hershey and Chase used to radioactively label the T2 phage's proteins?
32P
What is the function of bacteriophage?
The function of bacteria is to reproduce. Bacteria is a large domain of prokaryotic microorganisms. They are also the cause of human and animal diseases. Some bacteria, like those in the intestines are friendly and needed for digestion.
The head of T2 phage has DNA of molecular weight of 132 million the head of the phage is 10 nanometer long assuming the molecular weight of a nucleotide pair to be 660 calculate the length of the DNA?
please post this answer Did you copy this straight from your homework?
Hershey and Chase use what organism to show that DNA is the molecule that stores genetic information in living cells?
They used the T2 phage in their Blender experiment.
What virus is like T2 and infects bacteria?
This virus is a bacteriophage. The word means bacteria eater.
How did Hersey and chase help build our understanding of genetics?
They used E. coli or Escherichia coli in their experiments
What did hershey and chase observe in the offspring bacteria?
Hershey and Chase observed that DNA is the identity of the hereditary material in phage T2. Hershey and Chase used radioactive labels to mark the protein of the bacteriaphage in one experiment and the DNA in another.

Hershey and Chase set out to determine what molecule served as the unit of inheritance They completed a series of transduction experiments in which E. coli was infected by a T2 virus Which molecular?
DNA
What was the goal of the Hershey-Chase experiment?
- A series of experiments conducted in 1952 by Alfred Hershey and Martha Chase confirming that DNA was the genetic material in cells - The experiment was conducted using T2 phage; a virus that infects bacteria. They do so by attaching to the surface of a bacterium and injecting its genetic material into the bacteria. The structure had recently been elucidated by electron microscopy. - The 1st experiment- Phage DNA was labeled with radioactive 32P. Phosphorous is an important component of DNA which is not found in Amino Acids; protein building blocks. - The phages were allowed to infect E.coli bacteria and through a series of elegant experiments they were able to observe transfer of labeled phage DNA into the cytoplasm of the bacteria. - In the second experiment, they labeled phages with radioactive Sulfur 35 which is found in amino acids cysteine and Methionine. After infection of E.coli, they sheared off the phage protein shells from the infected cells using high speed blender and centrifugation to separate. - After centrifugation, the radioactive sulfur was found in the protein portion confirming the hypothesis that the genetic information transferred was DNA and not protein
