Indicate whether each of the following descriptions applies to myosins (M), kinesins (K), or dyneins (D). Your answer would be a five-letter string composed of letters M, K, and D only, e.g. MMMDD.
( ) They have larger structures than the other two.
( ) They are generally faster than the other two.
( ) They are structurally unrelated to the other two.
( ) They walk on a different cytoskeletal filament than the other two.
( ) They are all minus-end directed.

Dyneins are fast, minus-end directed, microtubule-based motors that have large structures unrelated to those of kinesins (also microtubule-based) and myosins (actin-based) and are also faster than these other two motor proteins.
