Chapter 8, Problem 1DAA
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.
Before blending what percentage of each isotope. 35S and 32P, was extracellular (outside the bacteria)?

- TRY 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_forwardExperiment: DNA Extraction from Banana The procedures are attached below. Questions: 1.

- Transcribed Image Text:Complete the following tasks. You discovered that a species of bacteria can break down StyrofoamT (polystyrene) products due to an enzyme it produces, polystyrenase. You wish to study the gene that codes for this enzyme. Task 1: DNA Extraction To begin work on the bacterium, you begin by extracting its genomic DNA (GDNA). What is the purpose of the following procedures? Answer briefly but completely. Using sodium dodecyl sulfate, a detergent Answer: а. b. Adding RNase A and Proteinase K during extraction Answer: c. Adding ethanol before recovering the DNA extract С. Answer: Task 2: Polymerase Chain Reaction After purifying the gDNA extract, you want to isolate and amplify the polystyrenase gene. You perform PCR using the appropriate gene-targeted primers. What is the purpose of the following PCR components? Answer briefly but completely.

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.

Spin 1.5 ml of cells in a microcentrifuge at maximum speed (12,000 rpm) for 20s to pellet. Remove the supernatant completely with a Pasteur pipet or a plastic pipettor tip. The spins can be performed at 4C or at room temperature. Longer spins make it difficult to resuspend cells. 2. Resuspend pellet in 100µl GTE solution and let sit 5 min at room temperature. Be sure cells are completely resuspended. 3. Add 200µl NaOH/SDS solution, mix by tapping tube with finger, and place on ice for 5 min. 4. Add 150µl potassium acetate solution and vortex at maximum speed for 2s to mix. Place on ice for 5-15 min. Be sure mixing is complete. 5. Spin 3 min at 12,000 rpm to pellet cell debris and chromosomal DNA. 6. Transfer 0.4 ml supernatant to a fresh tube, mix it with 0.8 ml of 95% ethanol or 0.4 ml isopropanol, and let sit 2 min at room temperature precipitate nucleic acids. 7.
