Chapter 11, Problem 29P

A wild - type culture of haploid yeast is exposed to ethyl methanesulfonate (EMS). Yeast cells are plated on a complete medium, and 6 colonies (colonies numbered 1 to 6 ) are transferred to a new complete medium plate for further study. Four replica plates are made from the complete medium plate to plates containing minimal medium orminimal medium plus one amino acid (replica plates numbered 1 to 4 ) with the following results:

Chapter 11, Problem 29P, A wild - type culture of haploid yeast is exposed to ethyl methanesulfonate (EMS). Yeast cells are

a. Identify the colonies that are prototrophic (wild type). What growth information leads to your answer?

b. Identify the colonies that are auxotrophic (mutant). What growth information leads to your answer?

c. Identify any colonies that are his - ,arg - ,leu - .

d. For colonies 1 , 3 , and 5 , write “ + ” for the wild-type synthesis and “ ” for the mutant synthesis of histidine and leucine.

e. Are there any colonies for which genotype information cannot be determined? If so, which colony or colonies?

A phenylgalactoside-type compound, which yields galactose when enzymatically cleaved, was added as the sole carbon source to petri dishes containing E. coli culture medium. E. coli can utilize galactose for growth. Each of the following bacterial strains was plated on this medium and scored for growth after 1-2 days. Growth Genotype lacz+ lacI+ lacz+ lacIs lacz+ lacl- + oc lacZ+ lacI+ + a) What do you conclude about this compound with respect to its ability to be cleaved by ß- galactosidase? Why? b) What do you conclude about this compound with respect to its ability to inactivate the Lac repressor? Why? T
In the Avery, McLeod, McCarty Experiment where supernatant from heat killed, virulent S Strain pneumonia solutions were added to non-virulent R Strain pneumonia cell cultures and allowed to grow in liquid media (i.e., broth). In tubes where Protease was added to the supernatant prior to cell culture, what was the observed effect when plating and growing the S. pneumonia cells to solid media? Selected answer will be automatically saved. For keyboard navigation, press up/down arrow keys to select an answer. a b C d e All RNA was degraded and Transformation of the R Strain to S Strain occurred. All Protein was degraded and Transformation of the R Strain to S Strain occurred. All DNA was degraded and Transformation of the R Strain to S Strain occurred. All RNA was degraded and no Transformation occurred indicating RNA is the molecule of Transformation inheritance None of the above are true
In a nutrient medium that lacks histidine, a thin layer of agar containing ~109 Salmonella typhimurium histidine auxotrophs (mutant cells that require histidine to survive) produces ~13 colonies over a two-day incubation period at 37 ° C. How do these colonies arise in the absence of histidine? The experiment is repeated in the presence of 0.4 μg of 2-aminoanthracene. The number of colonies produced over two days exceeds 10,000.What does this indicate about 2-aminoanthracene? What can you surmise about its carcinogenicity?
