- A publication describes a kinesin molecule that is claimed to move along microtubules with a step size of 6 nm. You are skeptical. Why?arrow_forwardArrange the following terms in order of increasing specialization: Oligopotency, pleuripotency, unipotency, multipotency.arrow_forwardNeurofilament proteins assemble into long, intermediate filaments , found in abundance running along the length of nerve cell axons. The C-terminal region of these proteins is an unstructured polypeptide, hundreds of amino acids long and heavily modified by the addition of phosphate groups. The term “polymer brush” has been applied to this part of the neurofilament. can you suggest why?arrow_forward
- Which direction is exclusive to dyneins and which to kinesins? Motor proteins are required for the cell to operate normally. They are concentrating their attention on which structural protein.arrow_forwardArrange the following terms in order of decreasing specialization: oligopotency, pleuripotency, unipotency, multipotencyarrow_forwardActin filaments at the leading edge of a crawling cell are believed to undergo treadmilling. What is treadmilling, and what accounts for this assembly behavior?arrow_forward
- what is COGS? Explain it'sarrow_forwardBased on the motors moving along the microtubule in the center of the field, would you propose: That a single microtubule can accommodate motors moving in both directions, or not? That all of the motors moving along a single microtubule move at the same speed, or not?arrow_forwardIdentify the structures and functions of microtubule-based motor proteins, kinesins and dyneins.arrow_forward
- What direction is particular to dyneins and which is specific to kinesins? Motor proteins are necessary for the normal functioning of the cell. On what structural protein are they focusing their efforts?arrow_forwardWhat is the role of Centrioles?arrow_forwardDescribe the mechanism by which a motor protein moves along microtubules using ONE example. In your answer, provide details of experimental approaches that can be used to assess the activity of the motor protein.arrow_forward
