Melanosomes are specialized lysosomes that storepigments for eventual release by exocytosis. Various cellssuch as skin and hair cells then take up the pigment, whichaccounts for their characteristic pigmentation. Mousemutants that have defective melanosomes often have paleor unusual coat colors. One such light-colored mouse, theMocha mouse (Figure Q13–3), has a defect in the gene forone of the subunits of the adaptor protein complex AP3,which is associated with coated vesicles budding from thetrans Golgi network. How might the loss of AP3 cause adefect in melanosomes?
These all relate to the translation of genetic informationstored in mRNA into proteins and how chemical information inproteins imparts function to those molecules. Write a brief essaythat discusses the role of ribosomes in the process of translationas it relates to these concepts.
