In-Silicoanalysis of Human Insulin Gene for Mirror repeat sequences

Abstract

The genetic material contains all the instructions necessary for the development, functioning & regulation of biological processes. This is also considering as a regulatory molecule. The structure constitute by its unique pattern of bases make it unique for every living being consider from bacteria to human. The varied pattern of bases in genomes or genes represents different types of repeats. These repeats types constitute the major fraction of the genomes. Among varied types Mirror repeats (MR) play crucial roles in the genome especially in formation of H-DNA structure by Non Watson pairing. Some studies suggest that mirror sequences responsible for neurological diseases also. Now days in modern era of technology in silico techniques were develop to extract any type of repeat sequences from any gene or genome. The major focus of current work is on identification of mirror repeats (MR) from human insulin gene sequence using an in silico approach. The approach is refer to as FPCB (FASTA Parallel Complement Analysis) were utilized to extract MR sequences. From the current study a total no of 210 MR sequenced were identified in Human insulin gene. The identified repeats vary in their length and majority of them are imperfect in nature. The maximum no of MR were reported in the region 3 (40) & minimum is in the region 8 (8). In the remaining regions the no of MR sequences were lies in between maximum & minimum values. These sequences may be helpful in many molecular level studies.
