Propose a model that outlines, step-by-step, events that could generate the gradients of transcription factors shown in the lower panel of the figure below. The upper panel illustrates gradients formed during the first step - start here. The gradients are marked with letters or numbers and should be used to identify the gradients in your answer. A & B may or may not represent the same molecules in the lower panel (e.g., A may or may not become 1). All 4 "general lessons" of spatial regulation of gene expression by morphogen gradients must be illustrated in the answer. Relative protein concentration Ventral B Dorsal

I know the answer is e but can you thoroughly explain the answer choices? like what does constitutive, inducible, expressed mean? and how do these conditions come about?
If you were to remove the ER retrieval signal (KDEL) from protein disulfide isomerase (PDI), which is normally a soluble resident of the ER lumen, where would you expect the modified PDI to be located? Why?
The above answer did not address the question in the sense that the answer did not indicate which protein involved in the pathways could be measured in the nucleus of cells and be confident in the results? I reiterate the question as follows: You want to do a single Western blot to measure changes in signaling activity, regardless of which pathway is being activated. For which protein involved in these pathways could you measure the levels in the nucleus of cells and be confident in your results? Why?
Consider a batch culture of sphere-shaped bacteria in a growth medium or broth, in which the mean cell diameter of the bacteria is 2.0 μm (micron). Show all your calculations and assumptions in answering the questions below: What is the volume of one of these sphere-shaped cells, expressed in liters? If there are 3 x 10^12 cells in one liter of this culture broth, what percentage of the volume is occupied by bacteria and what percentage is occupied by the cell culture broth (water only)? If the cells contain 80% water, what is the dry cell concentration, expressed as “grams dry weight/Liter of broth”? You should assume that the density of the cells dry mass is approximately 1.0 gr/cm3
Find a method that uses some form of HPLC for the analysis of proteins. What was the stationary phase used? How does this kind of stationary phase separate the proteins? What kind of mobile phase was used? Was the method isocratic or was a gradient used? How were the proteins detected?
How can you tell if a protein is stably expressed over time by looking at a pulse-chase analysis gel with bands?
To construct an “interactome” like the one shown in Figure 9-21, scientists identify all of the protein interactions in a particular tissue or cell type. Comparison of interactomes from human muscle versus human brain tissue reveals very different patterns. If you were the scientist involved in this study, how would you explain these results?
Consider a bacterial strain that has a mutant lac repressor that cannot bind the operator. A. What will happen in the presence and absence of lactose? B. Will there be any difference if glucose is present or not? Explain your answer.
The receptor or drug target in this case was the rat GABAA receptor obtained from homogenised rat brain cortical tissue. Using the same radioligand binding technique, what other way could you look at ligand affinity to GABAA receptors without using GABAA receptors derived from homogenised tissue and What are the advantages/disadvantages to each strategy?
Using sickle-cell anemia as a basis, describe what is meant by a genetic or inherited molecular disease. What are the similarities and dissimilarities between this type of a disorder and a disease caused by an invading microorganism?
Briefly discuss the applications of k-mer analysis.
Consider the leucine transporter. Would Vmax and/or Kt change if you added a Na+ ionophore to the assay solution containing Na+? Explain.
