Abstract
10S RNA has been isolated from the postribosomal supernatant of rabbit reticulocyte lysate. This RNA is associated with protein in a ribonucleoprotein particle that sediments at approximately 20S. The 10S RNA extracted from this particle codes predominantly for alpha globin chains when it is translated by a mouse ascites cell-free extract. The product of the cell-free synthesis has been characterized by column chromatography and electrophoresis of the tryptic peptides. About 20% of the total alpha chain mRNA is present in the postribosomal supernatant, whereas beta chain mRNA is almost exclusively associated with polyribosomes.Entities:
