Gilmartin University of Vermont, Burlington, Vermont 05405, USA In principle, the formation of the 3 end of a eukaryotic for the evolution of two distinct 3 processing complexes mRNA is a simple process. At a minimum, it involves are likely to involve the conflicting pressures of post- the hydrolysis of a single phosphodiester bond in the transcriptional regulation: coordinate cell cycle control nascent transcript. For one unique class of mRNAs, tran- of the replication-dependent histone mRNAs versus the scripts of the metazoan replication-dependent histone developmental and cell-type-specific regulation of alter- genes, this is indeed the only requirement.
