The motor protein kinesin carries vesicles for long distances along microtubule tracks in the cell. Are the two motor domains of an kinesin molecule essential to accomplish this task, or could a one-headed motor protein function just as well? Please explain your response.

Answer #1

Kinesin transport molecules from center of cellto perifery and move on microtubule towards positive end. Here is the link for animation.

Yess 2 domines of Kinesin head essential to accomplish the task, because one motor head domine for MT binding another for ATP binding and hydrolysis. So thats all.

    please answer all that you can 1. You have genetically engineered green fluorescent protein (GFP) containing a KDEL sequence (GFP-KDEL). When GFP-KDEL is expressed in normal human fibroblasts and examined using fluorescence microscopy, the fluorescence appears diffuse across the cytoplasm. How would you explain this observations given that KDEL is supposed to be an ER-specific sorting sequence? A. This engineered GFP would not have a hydrophobic signal sequence to get it into the RER in the first place. B. The...

Microtubules are hollow rods about 25 nm in diameter and 200 nm to 25 um in length. Microtubule fibers are constructed of the globular protein A tubulin dimer consists of two slightly different polypeptides: a-tubulin and B-tubulin. Microtubules shape and support the cell and serve as tracks to guide motor proteins carrving organelles to their...
