Explain how positive control of transcription works including the functions of the activators and its effectors (inhibitor and inducer).
Mainly there are two type of proteins that regulate the transcription. These are activator and effector. Transcription factor when binds to the promoter region to initiate transcription are positive effector of transcription means they are activator as well as inducer. But when transcription factors binds to the operon gene it inhibit the transcription hence these are inhibitor.

In eukaryotic cells, there are specific transcription factors (activators) that regulate gene expression. Describe the organization of eukaryotic genes (i.e. promoters/enhancers) and how transcription factors are able to control gene expression and enzyme activity. a) Throughout the course we discussed the enzyme lactase and how it is differently regulated (and therefore expressed) in different human populations. Describe how this gene is differently expressed in different populations and when this/these change(s) are predicted to have taken place. b) Differential gene expression...
3) Gene Control in Bacteria - Transcription Activators and Repressors You are interested in examining the regulation of the gene that encodes an enzyme, Tre- ase, important in metabolizing trehalose into glucose in bacteria. Trehalose is a disaccharide formed of two glucose units. It is known that two DNA-binding proteins, TreA and TreB, are important for binding to the promoter of the Tre-ase gene and are involved in regulating the transcription of the Tre-ase gene: TreA binds to the "A"...
1. Describe how effectors of allostery regulate protein function based on positive and negative changes that take place in the protein. 2. Describe how ligand binding controls protein function by allostery 3. Describe the regulation of protein function based on quaternary structure 4. Propose how an inhibitor may or may not be an allosteric effector based on competitive, noncompetitive, and uncompetitive inhibition Describe quaternary structure based on subunits.
What are logical functions in Excel? Can you give an example and explain how it works?
The Centers for Disease Control and Prevention (CDC) explain how that organization works to address health issues in the world.
NF-kappa B (NFKB) proteins are transcription factors that control the expression of genes involved in cellular processes such as proliferation, differentiation inflammation, and apoptosis. Dysfunction within the NFkB pathway can trigger indefinite cell proliferation and cell survival leading to the development of tumors. Stimul OS NIYA W IDTNOM IMAM IMENOVE 1. Explain how NFKB proteins are activated to promote cell survival. 2. How would a cell evade apoptosis if an IB Inhibitor of kappa B) protein could no longer bind...
Explain how a triple-beam balance works. Would such a balance that functions properly on the earth yield the correct mass of an object on the moon? Why or why not?
Name the three pH control mechanisms in the body and briefly explain how each system works.
List the 4 functions of management. Explain how each function works with the others to satisfy the vision and mission for a sport organization. Use real world examples to support your answer.
Describe and explain a hypothetical microarray experiment used to compare transcription between control and estrogen-treated hepatocytes (liver cells). Assume there at 10 genes on the microarray, and that the mRNA from control cells is labeled with a red fluorophore and the mRNA from the estrogen-treated cells is labeled with a green fluorophore. Please answer the question in complete, clear sentences. Explain how you could tell if the expression of a gene was: a. the same for both samples. b. higher...
