1. Describe how a cell is able to sense glucose levels.
2. Jacob and Monod isolated bacterial mutants that had constitutive expression of the lac operon (on in either the absence or the presence of lactose). What gene or regulatory sequence could be affected in these mutants? How is the mutant function altered relative to the normal function?
3. Another class of bacterial mutants has normal lac operon regulation with regards to lactose (off in the absence of lactose and on in the presence of lactose), but abnormal regulation with regards to glucose such that the lac operon mRNA is expressed at a high level in either the absence or presence of glucose. What gene or regulatory sequence could be affected in these mutants?
4. Another class of mutants is considered "uninducible" as they cannot efficiently express the lac operon mRNA even in the presence of lactose and the absence of glucose. What gene or regulatory sequence could be affected in these mutants?
5a. Predict what would happen to regulation of the lac operon if the lacI gene were moved 50,000 nucleotides upstream of its normal location.
b. Predict what would happen to regulation of the lac operon if the CAP-binding site were moved 50,000 nucleotides upstream of its normal location.
It is a very curcial concept to understand how the immune response is mounted against viruses, bacteria, protozoans and helminthes. For an effective immune response, both innate and adaptive immunity should work together.
This Project report elaborates a critical review of important elements attached to Advanced Glycated End Products (AGEs). It is very crucial to understand the process called Millard reaction.
Soil stabilization is the permanent physical and chemical alteration of soils to enhance their physical properties. Stabilization can increase the shear strength of a soil and control the shrink-swell properties.
This assignment has three parts which contains questions related to Microbiology. It contains basic principles of microscopy, staining techniques in microbiology and microbial growth in the food industry.
Lipid metabolites are often seen as key elements in cellular signaling. Is this unique? Please provide several examples of the function of lipids as key elements in signal arrays and list the biologic functions these signals affect?
Please describe how one might search for chemical structure, biologic function relationships, involving small molecular weight lipophylic compounds. Provide one example.
Write a case study which detailing a scenario of a patient being investigated in the Haematology laboratory.
