Abstract
In vivo [methyl 3H]-labeled SV40 19S and 16S mRNA species were purified and their internal methylation as well as their capping structures analyzed. SV40 viral mRNA sedimenting in the 19S region contains approximately equal proportions of m7GpppAm and m7Gppm6Am, while the 16S mRNA contains mainly m7Gpppm6Am. N6 methyl adenosine is located internally within the RNA chains of both the 19S and 16S species.
摘要
在体内对[甲基³H]标记的SV40 19S和16S mRNA种类进行了纯化，并分析了它们的内部甲基化以及帽结构。沉降在19S区域的SV40病毒mRNA含有大致相等比例的m7GpppAm和m7Gppm6Am，而16S mRNA主要含有m7Gpppm6Am。N⁶甲基腺苷位于19S和16S种类的RNA链内部。
