Question 1.
Bacterial cells couple the process of transcription and translation. In eukaryotic cells, the process of transcription and translation are uncoupled or occur separately. Provide explanations as to why bacterial cells can couple the process of transcription and translation while in eukaryotic cells, the process is separated.
Question 2.
You're growing a culture of E. coli cells without glucose that has a mutation in the lac operator sequence such that it can't bind the lac repressor. Explain what would be occurring to the Lac operon in the presence of lactose. Explain what would be occurring in the absence of lactose.
Question 3.
You're studying a new protein and suspect that it may be a new type of transcription factor. You clone its sequence into a plasmid vector with a fluorescent tag so you can visualize its location. You observe that the new protein spends part of the time in the cell cytoplasm and part of the time in the cell nucleus. Describe a mechanism for its cytoplasmic retention and subsequent signal-mediated import. Design an experiment to test your hypothesis.
Question 4.
What is the histone code and describe what evidence there is both for and against this covalent modification of chromatin?
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.
