these results , along with earlier data obtained on l-cell heterogeneous nuclear rna methylation , are consistent with a model in which the nucleus is the cellular site of three mrna methylation events producing 5'-terminal m7g , the first 2'-o-methylnucleoside ( n 'm ) found in cap-1 structures and internal n6-methyladenosine .
