Some lower vertebrates such as fish and amphibians can control their color by regulating specialized pigment cells called melanophores.
 
  These cells contain small, pigmented organelles, termed melanosomes, that can be dispersed throughout the cell, making the cell darker, or aggregated in the center of the cell to make the cell lighter. You purify the melanosomes from melanophores that have either aggregated or dispersed melanosomes and find that:
 
  1. aggregated melanosomes co-purify with dynein;
  2. dispersed melanosomes co-purify with kinesin.
 
  Given this set of data, propose a mechanism for how the aggregation and dispersal of melanosomes occur.
