Bioinformatics being one of the novel disciplines of study poses challenges specifically for novice molecular biologists with a little mathematical background. The treatise has therefore been written in a most simplistic way rather in a layman¿s language for the comprehension of the post graduate students. The very knowledge, that author has acquired by reading mostly the literature pertaining to the subject for teaching an elementary course of Bioinformatics have been noted down. We suppose it will be very helpful for the beginners to grasp the most elementary concepts of bioinformatics specially for molecular biology related with sequence analysis and modeling.
