Question:
Which one of the following statements is TRUE for dynein and kinesin family of motor proteins?
Which one of the following statements is TRUE for dynein and kinesin family of motor proteins?
Show Hint
Dynein moves toward the cell center (– end), while kinesin typically moves away from the center (+ end), but can move in both directions depending on the type.
Updated On: Dec 11, 2025
- Both dynein and kinesin are only (+) end directed motors
- Dynein is (-) end directed and kinesin can be either (+) or (–) end directed
- Both dynein and kinesin are only (–) end directed motors
- Kinesin is (+) end directed and dynein can be either (+) or (–) end directed
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding motor proteins.
- Dynein moves along microtubules towards the minus (-) end, typically toward the cell center.
- Kinesin moves along microtubules towards the plus (+) end, typically away from the cell center, but it can also move toward the minus end in some cases.
Step 2: Conclusion.
Therefore, the correct statement is (B): Dynein is a (-) end directed motor, while kinesin can be directed to either end.
- Dynein moves along microtubules towards the minus (-) end, typically toward the cell center.
- Kinesin moves along microtubules towards the plus (+) end, typically away from the cell center, but it can also move toward the minus end in some cases.
Step 2: Conclusion.
Therefore, the correct statement is (B): Dynein is a (-) end directed motor, while kinesin can be directed to either end.
