You are studying a novel viral protein. There is nothing known about the function of this protein. You analyze the protein sequence you observe an N- terminal sequence that looks like a signal sequence. To determine whether this sequence is in fact a signal sequence you clone the gene and make a mutation in the sequence, changing all of the amino acids in that region to alanine. You then look to see if the protein binds SRP and is brought to the ER. If your hypothesis is correct and it is in fact a signal sequence you should get the following results to your experiment. Select the outcome that supports your hypothesis. WT = wild-type, unmutated protein M = mutant, protein with signal sequence mutated to alanines A. WT protein binds to SRP, localizes to ER M protein does not bind to SRP, is found in the cytosol B. WT protein does not bind SRP, localizes to the ER M protein does not bind to SRP, is found in cytosol C. WT protein does not bind to SRP, is found in the cytosol M protein…

What is the name of the technique that create this graph

Which of the following is an illustration of cell sorting? When dissociated epidermal and neural cells are mixed together, they will transdifferentiate and adopt a different fate A than their embryonic fate. When dissociated epidermal and neural cells are mixed together, they reaggregate and then segregate into two layers: B an epidermal layer and a neural layer. When dissociated epidermal and neural cells are mixed together, they can influence each other's development through paracrine signaling. Dissociated presumptive epidermal cells can spontaneously reaggregate after the dissociating agent has been removed. E When presumptive epidermal cells are isolated from the embryos, they dissociate spontaneously.

The middle lamella of plant cells is made of   Select one: a. A sugar called pectin b. A sugar called lignin c. A sugar called cellulose d. proteoglycans (GAGs)

If a percent difference is a positive number, what does this tell us about the change in weight of the artificial cell?

What is the best way to reduce “bleedthrough” when fluorescein and rhodamine are used simultaneously? A.Using a stronger excitation for rhodamine. B.Using an optimal combination of fluorescence filters. C.Using less rhodamine than fluorescein. D.By imaging each fluorescent molecule separately and waiting several seconds between each image, to ensure that all fluorescence has been emitted.
