You isolate a new natural product from a sponge. Because it is new and non-obvious, you suggest to your Pl that it should be patented. After filing an invention disclosure with the OIC, you are told it is not eligible for patenting without evidence that the compound is

On which of the following types of media would you expect untransformed bacteria to grow on? LB agar LB agar with ampicillin Untransformed bacteria will not grow on any type of medium. Untransformed bacteria will grow on all three types of media. LB agar with ampicillin and arabinose

You have several different media onto which you inoculated eight strains of yeast (A-H). The media include a rich medium, an unsupplemented minimal medium, and minimal media each supplemented with one vitamin. Of the yeast strains, one is a prototroph and seven are auxotrophs for a vitamin. After overnight incubation, the following results were observed (tan patches represent growth): D plate 1 (A) B DE F GH plate 5 plate 4 plate 6 Which plate contains an unsupplemented minimal medium? [Select] Which plate contains a rich medium? [Select] plate 2 Which strain is a prototroph? [Select] Strain E is an auxotroph for niacin. Which plate reveals this specific auxotrophy? [ Select] plate 3 plate 7 One strain is an auxotroph for both choline and pantothenic acid. Which one is this most likely to be? [Select]

Suppose you performed methylene blue staining on E. coli, and K. rhizophila and examined the stained bacteria under the oil immersion objective. Using the internet, background introduction, text references and other resources, draw the appearance of the cells on slides and above the drawing indicate the name of the organism and the magnification at 1000x with oil immersion.

25) Identify the most correct choice: a) ribosomes are the membrane bound organelles responsible for making proteins from RNAs. b) In gene therapy, Agrobacterium is the bacteria that transfers genetic material into the human cells that contain the mutated gene. c) spectrophotometer analysis can be used to detect the concentration of the dead cells in a solution only and not those that are living. d) None of the above.

In order to have a well-designed experiment, why would it be important to include the beaker of yeast and water.

Why does microbial polypeptide need to fold into a 3D protein in order to become functional? Explain in 1-2 sentences. Edit View Insert Format Tools Table

Which one of the following microorganisms would you use as a quality control check to ensure that your sterile technique method is properly working? S. aureus, a gram-positive bacterium E. coli, a gram-negative bacterium B. cereus, an endospore-forming bacterium M. leprae, an acid-fast bacterium T. pallidum, a flagellated, disease causing bacterium

Which of the following is NOT correctly matched?   A. Halophile – microbe that can grow in an environment with high osmotic pressure (e.g., salt) B. None of the other four answers (all are correctly matched) C. Agar – complex polysaccharide from seaweed used as a solidifying agent in culture media D. Colony – a population of microbial cells arising from a single cell or spore or from a group of attached cells E. Capnophile – microbe requiring an elevated molecular oxygen (O2) environment for optimal growth

You have a culture of bacteria with an unknown number of bacteria in it. You have at your disposal 10 1-mL pipettes, 3 dilution bottles that hold up to 100mL of volume, 3 test tubes that hold up to 10mL of volume, a graduated cylinder, an unlimited supply of distilled water. Explain how you would set up a 1: 10,000,000 dilution of your culture.
