title: The structural organization of nuclear messenger RNA precursor. I. Reassociation and hybridization properties of double-stranded hairpin-like loops in messenger RNA precursor.
abstract: The hybridization and renaturation properties of double-stranded hairpin-like loops isolated from giant nuclear messenger RNA precursor of mouse liver or ascites carcinoma cells were studied. About half of the hairpins in messenger RNA precursor appear to contain similar sequences, as indicated by the very fast kinetics of renaturation of the denatured double-stranded RNA sequences. These sequences have no tissue specificity. About one third of the hairpin sequences can hybridize to messenger RNA. It is suggested that the long hairpins in messenger RNA precursor play the role of sequences separating messenger RNA sequences from non-informative sequences and that these hairpins are recognized by processing enzymes.
