You isolate fragments of microtubules (red) and then add GFP (green) tubulin to the fragments. After a short incubation period, you put the resulting microtubules on a lawn of motor proteins and take an image. Then you add ATP and take another image. Which pair of images shows the result if the motor proteins is a dyein?

Step 1
This will result in a mixture where the microtubules are labeled with both red and green fluorescent proteins. Show more…

You are studying the function and behaviors (dynamics) of the dynein, NYC-1, in mature cardiomyocytes, which contain a lot of microtubules that NYC-1 dyneins can bind and move along. The walking speed of the dynein measures 1 ÎĽm/s in vitro. You made a cardiomyocyte cell line harboring a transgene encoding NYC-1::GFP, formed organoids (3-D culture) with the cell line, and imaged the dyneins under the wide-field epifluorescence microscope. However, your images were too blurry to analyze their subcellular localization and behaviors. Describe two possible causes of the blurry images, propose an alternative approach to yield better, clearer images, and describe how it works.

What would you expect to observe/not observe if the following modifications were made? Provide a brief explanation for your observation. 1. Colchicine, a microtubule-depolymerizing agent, was fed to adult female flies expressing the kinesin-β-galactosidase fusion protein (2 marks) 2. A mutation was included in the conserved ATP-binding motif of the kinesin domain preventing binding and hydrolysis of ATP (2 marks)

You are interested in the process of mitochondrial movement in neuronal cells. The graph below indicates the results of experiments you carried out in cells using the drugs colchicine and cytochalasin D. The graph shows the effects of these drugs on the relative anterograde mobility of mitochondria towards the axon terminus. Values are relative to the movement observed in the absence of either drug (control), which has been arbitrarily set to 100%. A) Based on the graph below, what basic conclusions can you draw about the type of cytoskeletal structures that support most of the mitochondrial movement observed within your cells? Include information about what type of motor proteins are likely to be involved in this transport and how you reached your conclusion. B) Both actin microfilaments and microtubules are capable of dynamic changes in length, which are influenced by the hydrolysis of a particular nucleotide triphosphate. Which nucleotide triphosphate is utilized by each of these cytoskeletal systems? What are the consequence of NTP hydrolysis for the dynamic behavior of actin and microtubules?
