A haploid strain of yeast is treated with a mutagen called EMS. The different steps in the treatment and the analysis are the following: Step 1: Two tubes, labeled A and B contain 0.2 ml each of same yeast liquid culture. The concentration of yeast cells in the liquid culture was determined by a measure of the turbidity of the culture. This concentration is 4.4 x 109 cells/ml. Step 2: In each tube (A and B) 1.5 ml of phosphate...

Problem solving Question: 1. If you were to serially dilute a sample with three 1:10 dilutions, what would be the final dilution of the last tube? 2. If you add 1 ml of sample to 99 ml of water, and then add 0.1ml (100pl) to the agar plate what is the dilution of the sample on the plate? 3. If you count 98 colonies on the 10-5 plate, how many bacteria/ml were in your sample? 4. What are three ways...

13. Yeast are eukaryotic, single-celled fungus (this is not part of this homework question, but you could test yourself by describing the carbon cycle around yeast). Yeast reproduce quickly (under optimal conditions, yeast cells can double their population every 100 minutes). Yeast signal to potential partners by producing an attractive pheromone - a chemical smell, but the effect of the strong signal depends on the environment. In Environment A, yeast with the strong signaling allele are preferred as mates, but...

How many colonies would be present on a plate after plating .5 mls of 10^-6 dilution liquid sample that contains 1x10^8 organism/ml? At 3:00pm, you inocculate 1x10^3 cells in a flask on nutrient broth. The cells have a lag phase that last an hour. At 8:00pm, the cultureenters stationary phase. At that time, there are 6.5x10^7 cells in the flask. Calculate the number of generations, the number of generations/hour and the doubling time or number of hours/generation.

Both of these are reasonably easy to solve with the "sandwich theorem" that you saw on the previous worksheet There, we said that we needed to find functions flow, thi that are lower and upper bounds for f, and that that had to be the case for all ED. This works, but it is really not necessary:...

Please show how to do these enumeration questions by showing the work. What is the dilution factor if you add 625 µL of culture to 4.375 mL of dilution medium? You count the 10-3 dilution of a yeast suspension using the 1/25 mm2 boxes : you find 45 cells in box 1, 15 cells in box 2, 42 cells in box 3, 23 cells in box 4, and 26 cells in box 5. a) What is the original concentration of...
