For bacteria that are F+, Hfr, F', and F- answer the following. a. Describe the state of the F factor. b. Which of these cells are donors? Which is the recipient? c. Which of these donors can convert exconjugants to a donor state? d. Which of these donors can transfer a donor gene to exconjugants? e. Describe the results of conjugation (i.e., changes in the recipient and the exconjugant) that allow detection of the state of the F factor in a donor strain. f. Describe a "partial diploid" and how it originates.

In the Meselson experiment, would it have been possible to utilize N14 in the original bacteria and only allow growing bacteria to access N15 to build new (F1) bacteria and get the same results? Explain why. (I need an answer in full complete sentences with the question restated in the response.)
You take 10 ml of a stock solution, which is at a concentration of 1000 phage/ml, and dilute it to a total of 100 ml. From the resulting solution you take 5 ml and dilute it to 25 ml, and from the latter you take 5 ml and make a total of 20 ml. a) It will be possible to know how many bacteriophage particles there will be in 1 ml of the last solution b) What is the dilution factor in each step, in the same order in which the dilutions are made? c) What is the total serial dilution factor?
In Hershey-Chase experiment, bacteriophages protein coats were tagged with radioactive isotope S-32. These phages were used to infect E. coli cells and the cells were further centrifuged to form pellets. Why was the radioactivity level of S-32 found greater outside the cells compared to the E. coli cell pellets? Explain briefly. If the experiment is repeated in the same manner but this time the phage protein coats are labelled with isotope X and the phage DNA with isotope Y, which isotope’s radioactivity will be found in greater amounts in the E. coli cell pellets after centrifugation? Explain briefly.
Draw a diagram/figure to explain the conjugation process (e.g. use PowerPoint or draw one by hand and include a photo of it). You should include in the diagram the F- recipient, Hfr Donor and the transconjugant/recombinant recipient. Make sure to include the genes encoding for Leucine, Threonine, Thiamine and Streptomycin resistance in your diagram. How does an Hfr strain of coli transfers chromosomal DNA to an F- strain? What determines how much of the chromosomal DNA is transferred?
Imagine that you are a student in Alfred Hershey and Martha Chase’s lab in the late 1940s. You are given five test tubes containing E. Coli bacteria infected with T2 bacteriophages that have been labeled with either 32P or 35S. Unfortunately, you forget to mark the tubes and are now uncertain about which tubes is which. You performed their blender experiment and got the following results. Which tube out of these 5 contains E. Coli infected with 32P-labeled phage? Explain your answer.
In this problem, just put the order of the intermediates on the pathway, starting with P and ending with Z and explain your reasoning. (So to get you started, notice the class 1 mutants—and there is only mutant in this class, which is mutant #5—won’t grow on minimal medium, but will grow if you give it substance Z. However, giving it substances, p, w, x, or y won’t help. This means that the gene that is mutated lies on the pathway in a place that the Z substances is to its right and all the other substances are to its left. The easiest next one to look at is the line with 2 pluses, and then the line with 3 pluses, and then the line with 4 pluses).
You have isolated a strain of E.coli that is resistant to penicillin,streptomycin,chloramphenicol and tetracycline. You also observe that when you mix this strain with a strain that is sensitive to all four antibiotics, the new strain becomes resistant to streptomycin,penicillin and chloramphenicol but not tetracycline. Explain how this is so?

Unfortunately, you forget to mark the tubes and are now uncertain about which were labeled with 32P and which with 35S. You place the contents of each tube in a blender and turn it on for a few seconds to shear off the phage protein coats. You then centrifuge the contents to separate the protein coats and the cells. You check for the presence of radioactivity and obtain the following results. Which tubes contained E. coli infected with 32P-labeled phage? Explain your answer. Tube number Radioactivity present in 1 Cells 2 Protein coats 3 Protein coats 4 Cells 5 Cells

With respect to F+ and F- bacterial matings, answer the following questions: (a) How was it established that physical contact between cells was necessary? (b) How was it established that chromosome transfer was unidirectional? (c) What is the genetic basis for a bacterium’s being F+?
A group of genetics students mix two auxotrophic strains of bacteria: one is leu+ trp+ his− met− and the other is leu− trp− his+ met+. After mixing the two strains, they plate the bacteria on minimal medium and observe a few prototrophic colonies (leu+ trp+ his+ met+). They assume that some gene transfer has taken place between the two strains. How can they determine whether the transfer of genes is due to conjugation, transduction, or transformation?
Type S Streptococcus pneumoniae bacterium is lethal and will kill its host. If heat inactivated the S strain dies and becomes nonlethal. Type R Streptococcus pneumoniae is a nonvirulent strain of bacteria. What would occur if one were to inject both the R strain and heat-killed S strains into a host organism such as the mouse? The R strain would be transformed into the virulent S strain and kill the host. Neither the S nor the R strain would change. The R strain would be transformed into the virulent S strain and not affect the host. The S strain would be transformed into the nonvirulent R strain and not affect the host The S strain would be transformed into the nonvirulent R strain and kill the host.
