Abstract
Vaccinia virus DNA contains a long inverted terminal repetition of MW approximately 6.8 x 10(6). A fragment of MW 6.3 X 10(6) from this repetition has been cloned in coliphage lambda and used to isolate RNA from virus-infected cells. Electron microscopy indicates that early RNAs are transcribed from the repeated sequence and cell-free translation shows that the RNAs code for polypeptides.
