WebThe fraction of hnRNA converted to mRNA [cytoplasmic poly(A)+RNA] has been measured for the two cell types by comparing initial rates of labeling of hnRNA with initial rates of appearance of labeled mRNA in the cytoplasm. While 20% of the Drosophila hnRNA is converted to mRNA, only 3.3% of the Aedes hnNRA is converted to mrRNA. WebThe hnRNA, which is longer than mRNA, contains both m 6 Ap and caps but 4–6 times as many m 6 Ap residues per chain. In addition, nuclear molecules contain T2 RNAase-resistant, methyl-labeled oligonucleotides (“di-” and “tri-” …
