The most abundant nascent poly(A)+RNAs are transcribed by RNA polymerase III in murine tumor cells
1990
Nucleic Acids Research
Preserved Fulltext
Twelve to twenty percent of newly synthesized poly(A)+RNA is transcribed by RNA polymerase Ill in Ehrlich ascites carcinoma and P301 plasmocytoma mouse tumors. ...
Several transcripts that hybridize with B2 probe were also observed in poly(A)-RNA. The major components consist of 180, 160, 120 and 95 nucleotides. ...
