Histones are presumed to be of chromosomal origin and provide
both structural and functional elements for chromatin. In like
manner the ribosomal proteins are of ribosomal origin and have
analogous roles. Considerable controversy over their cellular roles
exists because of the inability to compare directly both groups of
proteins. In...
