J. Uvelle Unuwing data, calculate the original cell density of the culture tested. SHOW ALL WORK. Plate 1 (105): 6421 colonies Plate 2 (106): 639 colonies Plate 3 (107): 68 colonies Plate 4 (108): 7 colonies 4. If you take lul of a 102 dilution and add it to 9.999ml H,O, what is the final DF? Show work. Experimental: Perform the serial dilution as seen below (9.9ml tubes=yellow top, 9.0 ml=blue) 1ml A 1ml A 1 ml A 100ul a...
2a. (4 pts) A potent mutagen was added to an E. coli culture growing in rich broth. Prior experiments established that this F cell line, designated WWU113, could not synthesize leucine. You are interested in measuring the rate of induced reverse mutation. You plan to grow a liquid culture of the leu strain and then plate various dilutions of the culture onto selective media. What media should you use to grow up the liquid culture? This will be Media A...
