- TOPIC: E. coli T4 (T4 Bacteriophage) Include a maximum of 3 sentences, a brief description of their growth. What are the structures responsible for growth and reproduction? What are their physical and nutritional (or chemical) requirements?Gram staining is a common technique used to differentiate two large groups of bacteria based on their different cell wall constituents. The Gram stain procedure distinguishes between Gram positive and Gram negative groups by coloring these cells red or violet. Gram positive bacteria stain violet due to the presence of a thick layer of peptidoglycan in their cell walls, which retains the crystal violet these cells are stained with. Alternatively, Gram negative bacteria stain red, which is attributed to a thinner peptidoglycan wall, which does not retain the crystal violet during the decoloring process - s. epidermidis a gram-positve coccus - E. coli a gram-negative bacillus - C. xerosis a gram-positive bacillus How does each organism fulfill a specific niche based on the information provided above?You are doing a viable cell count for a culture of E. coli you are growing in a flask. 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 factor

- The peptidoglycan layer in a Gram-negative cell is typically .008 um thick while the peptidoglycan layer in a Gram-positive cell can be up to 0.00000008 m thick. Which cell type has a thicker layer of peptidoglycan. The Gram negative cell is 1,000x thicker than the Gram positive cell. The Gram positive cell is 1,000,000x thicker than the Gram negative cell. The Gram positive cell is 1,000x thicker than the Gram negative cell. The Gram negative cell is 1,000,000x thicker than the Gram positive cell. The Gram negative cell is 10x thicker than the Gram positive cell. The Gram positive cell is 10x thicker than the Gram negative cell.If the generation time of Escherichia coli is 30 minutes, starting with 4 E. coli cells, how many cells can you obtain after 2 hours of growth?

- 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?The technique used to determine protein type or kind of protein in a membrane is called (type meaning for instance, peripheral or transmembrane protein, not a specific protein) thin layer chromatography with a protein specific antibody protein labeling with lactoperoxidase and radioactive iodine hydropathy with protein labeling SDS-PAGE with Western blot and protein specific antibodyUse the following information to answer the next question. Human genes were integrated into the chromosomes of pig sperm using the procedure of sperm-mediated gene transfer (SMGT). In the first successful SMGT procedure, scientists used an enzyme to integrate three human genes into the chromosomes of pig sperm. Approximately 90% of the resulting pig embryos carried all three human genes in very cell. The presence of the human genes in every cell of a pig embryo is evidence that the genes went through Select one: a. mRNA transcription b. DNA replication c. mRNA translation d. DNA transcription
