[The structure of nuclear pre-mRNA. VII. The hybridization and renaturation properties of double-stranded sequences of nuclear pre-mRNA].
Some properties of the double-stranded regions of pre-mRNA are discribed. 1. The double-stranded regions contain approximately 80 base pairs. 2. The material contains the heterogeneous populations of sequences and some homogenous material which renatures with a COT1/2 value of (1.5-3) X 10(-4). 3. Identical sequences of fast-renaturing "hairpins" may be found in various tissues. 4. Double-stranded RNA and mRNA have some sequences complementary to each other. These results consistent with the view that the hairpin sequences may act as specific recognition sites for ribonucleases involved in processing of pre-mRNA.
