Eukaryotic mRNA 5'-leader sequences have dual regions of complementarity to the 3'-terminus of 18s rRNA.

Abstract
We have used a microcomputer program to test eukaryotic mRNA 5'-leader sequences for complementarity to the 3'-terminus of 18S rRNA. No mismatched bases, bulge loops, or viral mRNA's were utilized. At least one-fourth of the more than 200 mRNA's studied were found to have two distinct regions of complementarity which resulted in an ability to bind to two separate rRNA regions (GAAGG and UUUGG). The analysis of 60 mRNAs with these dual sites resulted in a consensus structure that was a mean distance of 11.75 bases 5' from the initiator AUG and had an average predicted interstrand binding strength of delta G = -13.40 kcal. These characteristics compare favorably to those observed for the prokaryotic 16S rRNA-mRNA Shine and Dalgarno bond.
