- One of the early results shows that the post-centrifugation pellet of encapsulated cells also contains EA1 and/or Sap. Why is this not proof that Bacillus anthracis cells have both an S-layer and a capsule simultaneously? I need help finding the answer in the article and explain in short answer link to article: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC106848/One of the early results shows that the post-centrifugation pellet of encapsulated cells also contains EA1 and/or Sap.

I need help finding the answer in the article and explain in short answer link to article: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC106848/Below is shown a growth curve for an E. coli culture. As indicated, the culture was incubated in the absence of a carbon source for 2 hours until Glucose and Lactose were added; Glucose was used up after 5 hours, and Lactose was used up after 8 hours. During the time-course, you take four samples, labeled A-D, after 1, 3, 7 and 9 hours, respectively, as indicated under the graph. Assuming there is cAMP present at t=0, for each sample identify whether CAP and/or the Lac Repressor would be bound to the DNA, and explain why.

The volume of media in the flask is 1L. You took an aliquot directly from the media and diluted it using trypan blue. Here are the numbers that you get: squares counted: 4 total cells counted: 988 total viable cells counted: 960 THESE ARE THE QUESTIONS: What is your cell viability? What is the total number of viable cells in your flask? Show all work. Given: Cell Viability = Viable Cells/Total Cells Cells/mL = Total Viable Cells/Coners Counted x 10,000 x Dilution factorSuggest an approach you would take to identify the pharmacophore in the following leadcompound which inhibits poly(ADP-ribose) polymerase-1 (PARP-1).
- Here is an image of a UV-irradiation (wavelength 254nm) experiment performed on a plate of E. coll after incubation. Which side of the plate do you think has a zero-minute' negative control? A or B or neither? Explain with proper reasoning.Using one of the graphs obtained with the medium II, name the different phases of the bacterial growth and indicate the starting and ending time points of these phases as well as the physiological characteristics of the bacteria during each phaseYou 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?
- Which of the the following results of the extracellular enzyme tests is FALSE? Question 3 options: A Liquid gelatin positive for gelatinase B Clear area around bacterial growth on a starch plate after iodine is added means amylase is present C Clear zone around bacterial growth on a milk plate means caseinase is present D Solid gelatin after is positive for gelatinase E No clear zone around bacterial growth on milk plate means absence of casienaseA Manton-Gaulin homogenizer is used for cell lysis. Which of the following are true? Increasing the number of passes can increase fine cell debris and make subsequent clarification more difficult. Cell growth conditions and phase of growth at which cells are processed can impact cell disruption. Decreasing temperature can increase protein release. Decreasing pressure reduces the number of passes required. Explain what is meant by the extent of cell disruption is 0.9.Here is an image of a UV-irradiation (wavelength 254nm) experiment performed on a plate of E. coli after incubation.
