Reovirus inhibition of cellular DNA synthesis: role of the S1 gene.

abstract：:The 70S RNA of Rous sarcoma virus contains 4S RNAs which serve as primers for the initiation of DNA synthesis in vitro by the RNA-directed DNA polymerase of the virus. We purified these primers in three different ways-by isolation of the covalent complex between primer and nascent DNA, by differential melting of the 7...
