previous studies have shown that endogenous class iii rna polymerase ( s ) in nuclei from adenovirus 2-infected cells synthesize virus-coded rna species which are approximately 200 ( v200 ) , 156 ( v156 ) , and 140 ( v140 ) nucleotides in length ( weinmann , r. , brendler , t. g. , raskas , h.j. , and roeder , r. g. ( 1976 ) cell 7 , 557-566 ) .
