1962 J. R. Warner et al. in Science 28 Dec. 1399/2 We have been able to show that the site of hemoglobin synthesis in vivo is not the single ribosome but rather a cluster of ribosomal particles, which we have called a ‘polyribosome’ or simply a polysome.
1973 Sci. Amer. Apr. 41/1 As the synthesis of the messenger RNA proceeds, giving rise to a longer strand of RNA, more ribosomes attach themselves to the strand. They form a string called a polyribosome, which continues the translation of the elongating messenger RNA.
2001 Proc. National Acad. Sci. U.S.A. 98 12027/1 Peroxisomal matrix enzymes are synthesized on cytosolic polyribosomes.
