The first direct measurement of a motor taking single steps was an analysis of _______ stepping using _________.
A)myosin,optical trap technology
B)dynein,ion exchange chromatography
C)kinesin,optical trap technology
D)kinesin,ion exchange chromatography
E)dynein,polyacrylamide gel electrophoresis

Question

Quizplus · Accepted Answer

The first direct measurement of a motor taking single steps was an analysis of kinesin stepping using optical trap technology. This is stated in various research articles and textbooks on molecular motors. Option A is incorrect because it refers to myosin, which is a different motor protein. Option B is incorrect because ion exchange chromatography is not a method used for measuring single steps of molecular motors. Option E is also incorrect because polyacrylamide gel electrophoresis is a method used for separating and identifying proteins, but not for measuring single steps of molecular motors.
