title: Characterization of the branch site in lariat RNAs produced by splicing of mRNA precursors.
abstract: The branch site of lariat RNAs produced during the splicing of the first two late leader exons of adenovirus-2 has a structure of (formula; see text) There is a distinct complementarity between sequences preceding the adenosine at the branch site and the 5' terminus of the intervening sequence.
