- In Figure 6-13, explain at the protein level why this heterokaryon can grow on minimal mediumA media contains 2 E. coli cells which have a generation time and a replication time of 60 and 40 mins respectively. How many cells will be produced after 5 hours?You got an opportunity to join a professor lab who is working in-vivo model and specifically looking at the dysregulation of mitochondria in liver. He asked you to isolate mitochondria from a Rat liver and placed in an assay medium. Based on the knowledge you gain in this course so far, please answer the following questions: a) Which technique will you use to isolate mitochondria? b) What happens to the pH of the medium when the medium is kept anaerobic? c) What happens when O2-saturated saline is added to the mixture?
- Please I don’t understand this Biochem question. An explanation leading to both of the CORRECT answers would be helpful!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?Why are chloroplasts and mitochondria shown as arrows originating from the Bacteria ?
- Why do we use an Electron Scanning Microscope to see bacteriophages over other microscopes?Bacteria and human beings are very different organisms. Why is it possible to combine their DNA and use a bacterium to make a human protein?Imagine that you are a student in Alfred Hershey and Martha Chase’s lab in the late 1940s. You are given five test tubes containing E. coli bacteria infected with T2 bacteriophages that have been labeled with either 32P or 35S. Unfortunately, you forget to mark the tubes and are now uncertain about which were labeled with 32P and which with 35S. You place the contents of each tube in a blender and turn it on for a few seconds to shear off the phage protein coats. You then centrifuge the contents to separate the protein coats and the cells. You check for the presence of radioactivity and obtain the following results. Which tubes contained E. coli infected with 32P-labeled phage? Explain your answer. Tube number Radioactivity present in 1 Cells 2 Protein coats 3 Protein coats 4 Cells 5 Cells
