Bioinformatics Study On Mirror DNA In Mycobacterium Tuberculosis Using Fast Parallel Complement Blast Strategy.

Abstract Many softwares that have been used for identification DNA mirror repeats were not simple and effective for finding mirror repeats so a new method for the identification of mirror repeats within the gene sequences in both eukaryotic and prokaryotic organisms has been developed and now is available. The method is called FAST PARALLEL COMPLEMENT BLAST which is the easiest method for observing mirror repeats in bacterial genome and other eukaryotic genome. This simple method involves only three steps Downloading sequence of mycobacterium tuberculosis gene using NCBI in FASTA format Making a Parallel complement and searching for mirror repeats using BLAST which shows the homology between the original sequence and the parallel complement sequence. We explored twenty genes 20 of Mycobacterium tuberculosis H37Rv for DNA mirror repeats and the result shows that mirror repeats of 18 genes were successfully found. Furthermore nobody knows the exact role of mirror repeats yet and detailed mechanisms and functions of most repeats are still unknown.
