The splicing function of these proteins is influenced by their location at exons or introns along the pre-mRNA. Located throughout the pre-mRNA are short, cis-acting motifs consisting of five to six ...

Phylogenetic analyses of two chloroplast and five putatively unlinked nuclear DNA regions were used to explore the evolutionary relationships of a circumpolar arctic polyploid species complex in ...
