This book has covered all the important topics of biology ranging from Universal Solvent "water" to recombinant DNA technology. The primary target audience for the book are undergraduate students and the students preparing for postgraduate entrance tests. This is not a book to replace the superb all-embracing and highly detailed Biochemistry textbooks that take the reader to the cutting edge of this science. Rather, its goal is to allow the reader to cut to the heart of the matter, to see what the core information is and readily to assimilate it. For mainstream biochemistry students, it may be seen as complementary to the large detailed textbooks, whereas for students taking biochemistry as an optional or elective module, it should be welcome as a fast way to become acquainted with the main facts and concepts.
