Method Computational analysis of a large UTR database: link
Comments Additional analysis of the same database suggests that the length of 3'-UTR increases with evolutionary age and, possibly, with organism complexity ( Fig. 5). By contrast, the 5'-UTR length is remarkably consistent in organisms ranging from fungi and plants to invertebrates and vertebrates, including humans.
