these results indicate that ( i ) cotranslational assembly of myosin heavy chains is developmentally regulated , ( ii ) structures containing actin and not microtubules may mediate initial association of the heavy chains with the cytoskeleton , and ( iii ) the site of translation dictates where a significant fraction of the heavy chains will be inserted into the cytoskeleton .
