Bacteria who had been infected
Experiment :
Radioactively labelled sulphur and phosphorus were used.
Radioactive sulphur + bacteria + virus = radioactivity detected in phage ghosts which are made up of proteins = it means proteins are not transferred from phages to bacteria
Radioactive phosphorus + bacteria + virus = radioactivity detected in bacteria into which virus had injected its genome = it means viral genome was transferred to bacteria
Conclusion of the experiment = DNA and not proteins, is the genetic material
Please rate high.

The Hershey Chase experiment using radioactively labeled bacteriophage to infect bacteria proved that DNA was the genetic material. If you were reviewing those experimental results, which of the following would provide evidence that DNA was the genetic material? Select all that would apply. a) The DNA was localized in the cytoplasm of the bacterial cell, which is the same site that the bacterial chromosome is located. b) Radioactively labeled viral proteins were only found outside the cell and the viral...

Please arrange the labels in their proper order with the images to assess your understanding of the part of the Hershey-Chase experiment that identified DNA as the "infectious agent of virus particles. Radioactive T2 phage particles are used to infect new E. coll cells. After a brief treatment in a blender, a sample is centrifuged to separate cells from T2 phage "ghosts" (outer protein structure). Radioactivity is found inside infected cells and not in ghosts New T2 phage particles are...

QUESTION 2 Hershey and Chase carried out an experiment to follow the movement of the bacteriophage DNA and proteins during infection and viral replication inside of the bacteria host. What is/are the evidence that DNA is the genetic material and not proteins? Choose the most correct answer. O A. The 32-P radioactivity is mostly found with the bacteria and not the supernatant. O B. The 32-P radioactivity is mostly found with in the supernatant and not the with the bacteria....

Book: ESSENTIAL BIOLOGY - Chapter 10 question; In a classic 1952 experiment, biologist Alfred Hershey and Martha Chase labeled two batches of bacteriophage one with radioactive sulfur ( which only tags protein) and the other with radioactive phosphorus ( which only tags DNA). In separate test tubes, they allowed each batch of phage to bind to nonradioactive bacteria and inject its DNA. After a few minutes, they separated the bacterial cells from the viral parts that remained outside the bacterial...

1. The type of genetic exchange between bacterial cells that can happen between isolated DNA and a live bacterial cell is: a. conjugation b. transduction c. transversion d. transformation 2. An Hfr strain of E. coli with genotype a+b+c+d+e+f+ is mated with an F¯ auxotrophic strain with the genotype a¯b¯c¯d¯e¯f¯. Conjugation is stopped at 10 minute intervals and the genotypes of the resulting conjugants are determined. The following results are obtained: after 10 minutes e+ after 20 minutes a+ e+...
