If you clone a structural genes of the Yersinia pestis type III secretion system into harmless E. coli, knowing that this E. coli strain will not become a human pathogen. Please give and explain the two causes for this.
Homework Answers
The type III secretion system is seen in Y.pestis and also in E.coli.
Since it is already mentioned that the E.coli is harmless, it indicates that the E.coli is not enteropathogenic or enterohemorrhagic. Only these kinds of E.coli can harm the human host.
The mode of action of both bacteria are different. Y.pestis mainly concentrates on immune cells of the host while E.coli concentrates on the intestine epithelium.

You have isolated a strain of brewer's yeast (Saccharomyces cerevisiae) in the lab for your second job at a hip new microbrew (you make a great IPA). You find that this strain ferments more efficiently and adds a superior flavour profile to your brews. You want to clone the strain of yeast and generate a genomic library to determine the genes responsible for this finding. To do so you: 1. Obtain fragments of the whole yeast genome (DNA) through restriction...

As you may remember from basic biology, the human A/B/O blood type system is controlled by one gene for which 3 variants (“alleles”) are common in the human population – unsurprisingly called A, B, and O. As with most genes, everyone has 2 copies of this gene, one inherited from the mother and the other from the father, and everyone passes a randomly selected copy to each of their children (probability 1/2 for each copy, independently for each child). Focusing...

III. You isolate a new species of bacteria that only grows in the Antarctic. A wild type strain of this bacteria can synthesize its own alanine (alat) and its own tryptophan trp' ), both of which are essential amino acids. A mutant strain of the same bacterium cannot synthesize either of those two amino acids (ala trp'). You are interested in the degree of linkage between the ala and the trp genes in this new bacterial species. Fortunately, this species...

To place the E. coli replication system on the human scale, imagine that the DNA strand type B has a diameter of 20 angstroms and that it expands to 1m in diameter. If this expansion happened for the holoenzyme DNA polymerase III, it would be about the size of almost half a truck. In this expanded system. (a) How fast each replisome would move. (b) How far would each replisome travel? (c) What size would an Okasaki fragment be? (d)...

1. (a) Microorganisms can be used to remove chemical pollutants from the environment. ine gene cluster xyl encodes several enzymes that are involved in degrading toluene, and transcription of these genes is activated when the xylS protein (expressed continuously under a constitutively active promoter p) binds to toluene. Only then can the resulting xyls/toluene complex bind to the pm promoter to activate transcription of the genes in the xyl cluster. By considering the cellular location of the enzymes that degrade...
