The research has three objectives: 1) Produce transcriptome assembly and annotation of T.This trick earned the species its nickname as the immortal jellyfish, a term Graham admits is a bit hyperbolic. The study was aimed at understanding what made this jellyfish different by comparing the genetic sequence of T dohrnii to that of Turritopsis rubra, a close genetic cousin that lacks the ability to rejuvenate after sexual reproduction.Further, we compare a set of almost 1,000 genes related to aging and DNA repair between both Turritopsisand other cnidarians and present a stage-specific transcriptome of life cycle reversal process of T. dohrnii. Altogether, these results unveil key molecular mechanisms behind rejuvenation of T. dohrnii. Abstract.
