Web13 apr. 2012 · The intron–exon architecture of many eukaryotic genes raises the intriguing question of whether this unique organization serves any function, or is it simply a result of the spread of functionless introns in eukaryotic genomes. In this review, we show that introns in contemporary species fulfill a broad spectrum of functions, and are involved in … WebMushrooms have at least ten different isoforms of tyrosinase. While the reason so many isoforms exist is not known, it is known that they differ in enzymatic activity and tissue specificity. In this lab, you will identify and enrich the isoenzymes present in different tissues of the Portobello mushroom.
