Research Paper on the Evolutionary History of Reverse Transcriptase
Ria researched the evolutionary history of reverse transcriptase which catalyzes the transcription DNA into RNA, and is found in viruses like HIV. 130 reverse transcriptase sequences were chosen to represent the larger array of diverse sequences that exist, such as telomerase enzymes, viral reverse transcriptase enzymes, and the retrotransposon reverse transcriptases. All of the sequences were aligned and compared using a phylogenetic tree which highlighted the similarities between the proteins. To investigate further, the telomerase groups, animal and plant telomerases were represented by the human telomerase and the Tetrahymena thermopylae telomerase, respectively. The structures of the two chosen telomerases were compared more closely according to orientation and conservation. Both methods of comparison were used to identify new information about the reverse transcriptase evolutionary process.
