Computational Analysis Of Papionini Evolution Using Alu Insertions, Vallmer Edward Jordan Ii

LSU Doctoral Dissertations

Alu elements are primate specific retrotransposons that have remained active throughout the course of primate evolution. As a result of this sustained mobilization. Alu elements are present in greater copy number in primate genomes than any other transposable element. An average of over one million Alu elements has been identified in every sequenced haplorrhine genome to date. These characteristics qualify Alu elements as ideal characters for studying evolutionary relationship among primates.

The increasing availability of whole genome sequencing data presents novel challenges and opportunities for comparative genomic analyses. Genomic data is now publicly available for most primate species. Such an …

An Analysis Of Alu Elements In Baboons, Cody James Steely

LSU Doctoral Dissertations

Transposable elements compose a large portion of mammalian genomes and are estimated to make up anywhere from ~45% - ~70% of the human genome. Alu elements are primate-specific retrotransposons that are found in high copy number (> 1 million copies) and are spread throughout the genome. These elements are the most commonly repeated sequence in the human genome and have contributed to a number of disease states in humans. Alu elements are useful markers for population genetics and phylogenetics and have proven valuable in understanding difficult to determine relationships between species and within populations.

Baboons (genus Papio) are spread throughout …

Evolution Of Alu Elements In The Saimiri And Papio Lineages Of Primates, Jasmine Nicole Brown Baker

LSU Doctoral Dissertations

Alu elements are approximately 300 base pair (bp) primate specific non- autonomous retrotransposons. Alu elements, a short interspersed element (SINE), account for high copy numbers in all primate genomes. Numerous Alu element subfamilies have undergone varying degrees of activity and amplification within primates. Identification of these subfamilies has proved to be very informative in elucidating phylogenies and as phylogenomic markers. Squirrel monkeys, genus Saimiri, are one of the most well-known neotropical primates and the second most commonly used laboratory monkey. Squirrel monkey species diverged approximately 1.5 million years ago and are native to South America. Despite being well-known, there …
