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 answers are as following:

1. c. double helix, nucleosome, coil, supercoil, chromosome

2. b. g2 phase, preparation for mitosis

3. d. interphase consists of the g1, s, and g2 phases

4. c. metaphase

5. a. chromosomes are duplicated before cell division so that each new daughter cell has a complete set
