Part A Microtubules are filamentous structures in cells that maintain cell shape and facilitate the movement of molecules within the cell. They are long, hollow cylinders with a diameter of about 25 nm. It is If the emitted light has a wavelength of 550 nm and the NA of the microscope objective is 1 5, what is the smallest resolvable possible to incorporate fluorescent molecules into separation between two objects in the microscope? microtubules, when illuminated by an ultraviolet light, Express your answer with the appropriate units. the fluorescent molecules emit visible light that can be imaged by the optical system of a microscope.
