D)electron microscopy.

Question

Quizplus · Accepted Answer

Fluorescence speckle microscopy is the most suitable option to observe treadmilling through kinetochore microtubules. This technique involves labeling microtubules with a fluorescent protein and observing the dynamic movement of the labeled proteins using a fluorescence microscope. The dynamic movement of the speckles can reveal the movement of the microtubules, allowing for the observation of treadmilling. Simple fluorescence microscopy does not have the resolution or specificity to observe the dynamic movement of microtubules. Optical trap microscopy is used to observe mechanical forces on microtubules, but is not well-suited to observe the dynamic movement of microtubules involved in treadmilling. Electron microscopy can provide high-resolution images of microtubules, but cannot capture the dynamic movement of these structures involved in treadmilling.
