Quizplus · Accepted Answer

Tubulin is a component of microtubules, which are present in the spindle fibers (2) during cell division and in the cilia and flagella (3) for movement. Tubulin is not typically present in the plasma membrane (1) or the nuclear envelope (4), so those structures are unlikely to show tagged tubulin. Therefore, option B, 2 and 3 only, is the best choice.
