Chapter 22, Problem 16P
In Fig. 22.14c, the fw2.2 causal gene was validated by introducing the S. pennellii version of the gene into S. lycopersicum. Why was the experiment done this way, rather than the other way around?

Which of the following best describes the control group for this experiment?
a) mating between male flies raised on maltose medium and female flies on starch medium.b) mating between male and female flies raised on starch medium in different populations.c)mating between female flies raised on maltose medium and male flies raised on starch medium.
In an imagined transduction experiment with alleles a+, b+,and c+, a+ alone was transduced into an auxotroph 800 times, b+ alone 1200 times, and c+ alone 1500 times. Genes a+ and b+ were both found 3 times, b+ and c+ 12 times, and a+ and c+ one time. What can you conclude regarding the linkage of the three alleles (which is two are closer together).
Help me please i will rate
When the S.cerevisiae genome was sequenced and surveyed for possible genes, only about 40% of those genes had been previously identified in forward genetic screens. This left about 60% of predcited genes with no known function, leading some to dub the genes fun (function unknown) genes.
a)As an approach to understanding the function of a certain fun gene, you wish to create a loss of function allele. How would you do this?
b)You wish to know the physical location of the encoded protein product. How would you obtain such information?

In one experiment, they mixed cells of Hfr strain AB-312, which were xyl+ mtl+ mal+ met+ and sensitive to phage T6, with F− strain AB-531, which was xyl− mtl− mal− met− and resistant to phage T6. The cells were allowed to undergo conjugation. At regular intervals, the researchers removed a sample of cells and interrupted conjugation by killing the Hfr cells with phage T6. The F− cells, which were resistant to phage T6, survivedand were then tested for the presence of genes transferred from the Hfr strain. The results of this experiment are shown in the accompanying graph. On the basis of these data, give the order of the xyl, mtl, mal, and met genes on the bacterial chromosome and indicate the minimum distances between them.arrow_forward

Each Hfr strain was found to transmit its genes in a unique sequence, as follows (only the first six genes transmitted were scored).

- The map below was constructed using information from an interrupted mating experiment. Str# refers to the strain numnber from which the data were obtained. The strains that are referenced by the Str#'s on the map are considered to be F+ strains. The units for the map distance values on this map are minutes Assume that four genes were transferred by each strain in the interrupted mating experiment. Based on this map, list in order of transfer (first to last) the genes transferred by Str4.

Wildtype X has an LD50 value of 10 bacteria when administered to mice by inhalation. Using transposon mutagenesis, the researchers have isolated two mutants of X that they call Xmut1 and Xmut2, both of which have LD50 values of 105 when inhaled by mice. However, in tissue culture cells, Xmut1 can invade the cells just as well as wild-type X, while Xmut2 cannot. Provide a possible explanation for these results.arrow_forwardPenicillin was first used in the 1940s to treat gonorrhea infections produced by the bacterium Neisseria gonorrhoeae. In 1984, according to the CDC, fewer than 1% of gonorrhea infections were caused by penicillin-resistant N. gonorrhoeae. By 1990, more than 10% of cases were penicillin resistant and a few years later the level of resistance was 95%. Explain the various ways this resistance could be spread among the cells. Could this resistance pass to other infectious bacteria from N. gonorrhoeae?arrow_forward
