The molecular and cellular level investigation provides us accurate guidelines to reach an appropriate decision regarding the research/ diagnosis. The scientists may then be more confident to design an accurate therapy plan. That also potentially helps to offer quality clinical and pharmaceutical care. Moreover; the microbial infectious diseases demand an integrated and valid collection of simple and conceptual informations, which support the researchers to elaborate the molecular cell pathology. The molecular biology explores the morphology, function, genome organization, regulation of genetic expression, morphogenesis, and somatic cell genetics. Thus, we have carefully tried to present the latest and authenticated informations which help to improve the scientific skills and minimize the complications of polypharmacy/ multi disease therapies. Additionally, it is also vindictive reality that, currently we are offering substandard clinical facilities and poor pharmaceutical care, especially in developing part of the world. That potentially needs attention to save the innocent live (including Pakistan).
