The book Basics of Molecular Biology has been kept close to the basics as far as possible; so that the students may learn without having to first assimilate complex terminology. The book contains essential facts and overloading it with esoteric details only of interest to a minute proportion of the scientific community has been avoided. The book contains more than 100 line diagrams which are easy to understand memorize and reproduce at a later date. This is invariably useful while explaining a difficult concept to others as well as during examinations.
