POLYRIBOSOMES: SIZE IN NORMAL AND POLIO-  INFECTED HELA CELLS.
HeLa cells normally contain a distribution of polysome sizes, and the largest polysomes contain over 40 ribosomes. After infection with polio virus and actinomycin-D treatment, a new class of polio-induced polysomes are found, some of which contain up to 60 ribosomes. Examinaton of these polysomes suggests a mechanism for protein synthesis with this polycistronic RNA.
