Chapter 8, Problem 2DAA
Hershey–Chase Experiments The graph shown in FIGURE 8.5 is reproduced from an original 1952 publication by Hershey and Chase. Bacteriophage were labeled with radioactive tracers and allowed 10 infect bacteria. The virus–bacteria mixtures were then whirled in a blender to dislodge any viral components attached to the exterior of the bacteria. Afterward, radioactivity from the tracers was measured.
FIGURE 8.5 Detail of Alfred Hershey and Martha Chase’s 1952 publication describing their experiments with bacteriophage.
“Infected bacteria” refers to the percentage of bacteria that survived the blender.
After 4 minutes in the blender, what percentage of each isotope was extracellular?

What observation led Hershey and Chase to the conclusion that DNA, not the protein coat, carried the genetic information needed to make new virus or phage particles?
Select one:
a. The cell membrane of the bacteria infected with a virus tagged with radioactive phosphorus exhibited radioactivity after it’s initial cell division.
b. Bacterial cells infected with viruses tagged with radioactive phosphorus were radioactive, indicating viral DNA entered the host cell.
c. The cell was vigorously shaken, causing the protein coats to detach from the cell membrane of the bacteria. The protein coats contain genetic information.
d. Bacterial cells infected with viruses tagged with radioactive sulfur were radioactive, indicating viral protein entered the host cell.

- How do you answer these two questions?arrow_forwardTRY TO KEEP IN SHORT AND USE OWN WORD FOR THIS QUESTION You are studying a type of bacteria isolated from the acidic water runoff of a mining operation. You subject two batches of the same bacteria type to different environmental growth conditions. One batch is grown at pH 2, while the other is grown at pH 7. All other environmental parameters are kept identical between the two batches. You then collect their proteins and run a Western blot using an antibody that binds to a proton efflux pump protein (which actively expends energy to pump protons out of a cell). How would you characterize the information obtained in this experiment? What does it tell you, and why is that potentially valuable information?arrow_forwardHello which one can be the right answer?arrow_forward
- did i identify sample a correctly? or is it actually none?arrow_forwardProcedure: 1. Using the DNA provided transcribe DNA into mRNA. 2. Use the mRNA strand you created and break it up into codons. 3. Plug the codons into the amino acid chart to determine the correct amino acid needed to build that protein. 4. Identify the protein you made by comparing the sequence to the pictures 5. Answer the questions for each protein molecule you build before moving on to the next. Protein 1: DNA A AGACCGTATAC mRNA Amino Acid Sequence 1. Which kind of protein molecule did this gene make? 2 How does this protein help the body maintain homeostasis2arrow_forwardChoose any two of the topics (experiments) outlined below.

When I read it myself, I do not understand exactly what is meant by the article. It would be nice if you could highlight the important points. You can use them in a figure or diagram to explain. thank you and hava a nice day :) Article: Biomimetic Engineering of Nanodelivery Systems: Artificial Viruses in the Making In an effort to engineer the next generation of nanoscale vectors, scientists have moved from using inorganic components aimed at obtaining inert structures to utilizing biological building blocks that are able to convey additional functionalities to the resulting construct. To cope with the complexity of the body and to evade the multiple layers of defense that tissues and organs have, it is critical to rely on the ability of certain materials to interact with, rather than to eschew, the biology of our body. Every NP system conceived to date faces one common fate: whether injected,…arrow_forward
- biotechnology lab class :1. The bacterial streaking on antibiotic containing agar plates has been completed and the plates will be available for you to inspect in the lab class.2. You will complete a restriction enzyme digest on the four available plasmid stocks and then examine the products by agarose gel electrophoresis. Photographs of the gel are attached to identify the plasmid present in each analysed sample.Now consider the following questions :- For each of the four plasmids used in the practical, identify the size (in kb) of the linear DNA fragment(s) that you would expect to obtain if the EcoRI digest is complete.- Using the provided negative image of the gel, which shows the bands present in the ND and D samples for each plasmid, identify the plasmid that was present in each of the four plasmid stock.- Explain how you were able to identify plasmid in each sample using the gel, considering how linear DNA fragments of different length are separated by agarose gel…arrow_forwardA scientist isolates the DNA genome from a virus.
