What human activity provides a reasonable analogy for the movement of kinesin molecules along microtubules?a. running on a treadmill. b. climbing a rope hand over hand. c. shooting a fire hose at a beach ball. d. being one of many rowers in a boat .

The correct answer is - option. b climbing a rope hand over hand is correct

Explanation:

The movement of the kinesin molecules led by the head of one kinesin followed by the second one after another same as one hand moves on the rope at a time and followed by the other hand during climbing the rope.

The movement of the kinesin microfilament is due to the increased affinity by ATP of the head of the kinesin for the microtubule. However, the hydrolysis of ATP decreases its affinity so it slides or moves to the plus end.

the sugar-phosphate backbone forms the structural framework of nucleic acids, including dna and rna. this backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.
