Methylated nucleotides block 5′-terminus of HeLa cell mRNA
摘要:
The 5'-terminal oligonucleotides m7G(5')ppp(5')NmpNp and m7G(5')ppp(5')NmpNmpNp were isolated by DEAE-cellulose column chromatography after enzymatic digestion of 32P- or methyl-3H-labeled poly(A)" HeLa cell mRNA. The recovery of such oligonucleotides indicated that a high percentage of mRNA has blocked termini. The dimethylated nucleoside, N6, O2'-dimethyladenosine (m6Am), as well as the four...
