Evolution Of Gene Structure In Multicellular Eukaryotes, Maria Hester

Inquiry: The University of Arkansas Undergraduate Research Journal

We investigated the patterns of intron conservation in eukaryotes for five different genes. The genes examined were ribosomal proteins L8, S14 and S17, along with elongation factor 2B and triose phosphate isomerase. Intron conservation for S14, S17, and triose phosphate isomerase was determined for 32 species representing the major branches of multicellular eukaryotes. For 25 conserved introns 16 were phase 0, five were phase 1, and four were phase 2. Triose phosphate isomerase had five of nine conserved introns shared between plants and animals, where S14 had one of nine and S17 had one of seven. However, there were two …
