Analysis Of Novel Regulatory Region And Function Of A Young Drosophila Retrogene: Dntf-2r
Kunte, Mansi Motiwale (Biology, 2009-09-16)Dntf-2r is a young retroposed gene that originated from the nuclear transport gene Dntf-2. Here the function, quality and evolutionary origin of the regulation of this retrogene are explored. In Chapter 1, I introduce the ... -
Proteasomal Gene Duplications And Recruitment Of Testis Specific Expression In Drosophila
Sorourian, Mehran (Biology, 2008-09-17)Proteasome is a large multisubunit complex that degrades ubiquitinated proteins in a highly regulated manner in all eukaryotes. Two subcompartments of this subunit are the 19Scap and the 20S core particle with 19S acting ... -
Rcd-1 Related:a Positively Selected Retrogene With Spermatogenesis Function In Drosophila
Muliyil, Taniya (Biology, 2008-04-22)Gene duplication is one of the major forces in driving genome evolution. Our study focuses on a particular retrogene Rcd-1 related (Rcd-1r) that originated through retroposition of the parental gene Required for cell ... -
Sequence Evolution Of Recurrently Recruited Retroposed Genes In Drosophila And Their Possible Role In Meiotic Drive
Tracy, Charles David (Biology, 2009-09-16)Gene duplications are a valuable source of genetic information that can evolve under positive selection creating a new gene function without affecting the original function.A gene duplication mechanism is retroposition. ... -
The Spatial Ecology Of The Comanche Harvester Ant, Pogonomyrmex comanche (Hymenoptera: Formicidae)
Mayo, Ann BurgessBecause of the diverse roles ants play, it has been suggested that ants may be ecosystem engineers and so, may be useful in monitoring ecosystem function and health. Because ant activities are localized around their nests, ... -
Study Of The Expression Pattern Of A Possible Pseudogene And A Functional Retrogene In Drosophila
Bhardwaj, Aditi (Biology, 2007-08-23)Gene duplication occurs when a mutation leads to the copying of a region of DNA that contains a functional gene. After duplication, there will be two copies of the gene in the genome. Gene duplication can have deleterious ...
