Question

which motor protein(s) participate(s) in the movement of melanin granules in melanophores?

kinesin only
both dynein and kinesin
dynein only
myosin only
both myosin and kinesin

Explanation:

Melanophore pigment dispersion and aggregation are microtubule - based processes. Kinesin and dynein are microtubule motor proteins. Kinesin moves towards the plus end of microtubules, and dynein moves towards the minus end. They work together to facilitate the movement of melanin granules in melanophores. Myosin is an actin - based motor protein and not involved in this microtubule - based movement of melanin granules in melanophores.

Answer:

both dynein and kinesin
