Which of Following Properties of Microtubules is Correct

Question

Which of following properties of microtubules is correct?
A) made of myosin
B) made of actin
C) found only in the terminal web
D) another term for microfilaments
E) interact with dynein and kinesin

Accepted Answer

Microtubules are made of tubulin and are a component of the cytoskeleton. They interact with motor proteins like dynein and kinesin to perform important functions such as intracellular transport and cell division. Option A is incorrect because myosin is a motor protein that interacts with actin, not microtubules. Option B is incorrect because actin makes up microfilaments rather than microtubules. Option C is incorrect because microtubules are found throughout the cell rather than just in the terminal web. Option D is incorrect because microfilaments are another term for actin filaments, not microtubules.
