LAP Lambert Academic Publishing This book is an attempt towards bacterial strain identification of the same species with a molecular prospective.This study illustrates how the organism of same species differ from each other with reference to their habitat. RAPD is an outstanding method to identify the genetic heterogeneity of the same species. Generally DNA the genetic material undergoes modification as a result of which a new strain emerges out of the same species. Environment plays an important role for such kind of diversity.
