Transcription of human papovarirus BK superhelical DNA by Escherichia coli RNA polymerase yielded symmetric RNA with an average chain length of 1,3000 nucleotides. All regions of human papovavirus BK DNA were equally transcribed. At least four initiation sites were available to the procaryotic enzyme.
大肠杆菌RNA聚合酶对人乳头瘤病毒BK超螺旋DNA进行转录,产生了平均链长为13000个核苷酸的对称RNA。人乳头瘤病毒BK DNA的所有区域转录程度相同。原核酶至少有四个起始位点。
