Two simian virus 40 transcriptional promoter elements, the 72-base pair (bp) repeat and the 21-bp repeat region, induce chromatin structures of increased DNase I sensitivity when transposed elsewhere in the viral genome. The induction of a sufficiently long stretch of DNase I-sensitive chromatin leads to the appearance of a visible nucleosome-free region.
两种猿猴病毒40转录启动子元件,即72碱基对(bp)重复序列和21 bp重复区域,当转座到病毒基因组的其他位置时,会诱导出对DNA酶I敏感性增加的染色质结构。足够长的一段对DNA酶I敏感的染色质的诱导会导致出现一个可见的无核小体区域。
