What was the major conclusion of the Hershey and Chase bacteriophage experiments? What was the major conclusion of the Hershey and Chase bacteriophage experiments?
A. single gene directs the synthesis of a single polypeptide.
B. DNA, but not protein, is the genetic material.
D. DNA is a double helix.
C. The genetic material is located in the nucleus of cells
Homework Answers
B. DNA, but not protein, is the genetic material.
Bacterial cells with radioactive phage DNA released new phages with some radioactive phosphorus. The researchers concluded that PhageDNA entered bacterial cells, but phage proteins did not. Hershey and Chase concluded that DNA, not protein, functions as the genetic material of phage T2.

Biology -> Genetics Which of the following is a key aspect of the Hershey-Chase bacteriophage experiments? Group of answer choices all of the answers are correct If RNA is destroyed cells are transformed, rough bacteria do not kill mice labeling of components 32P only into DNA; only 32P enters cells and is passed on to progeny phage If DNA is destroyed cells are not transformed, only smooth bacteria kill mice

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...

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....

The bacteriophage used in this experiment reproduces by the
lytic cycle. Suppose a similar experiment were conducted with a
bacteriophage that uses the lysogenic cycle. How would the effect
on the infected bacteria MOST likely differ?
A. The bacteriophage would attach to the bacteria and reproduce
in the extracellular space.
B. The bacteriophage would become permanently dormant and
unresponsive to environmental cues for reproduction.
C. The bacteriophage would attach its genes to the bacteria’s
DNA, allowing its genes to be...
