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.
