Molecular Biology, 4/e by Robert Weaver, is designed for an introductory course in molecular biology. The text is geared not only toward presenting concepts of molecular biology, but also the experiments that led to those concepts. Guided by this experimental approach, Dr. Weaver has been published by National Institutes as well as National Geographic.
I used this book for my Molecular Biology and Genetics class as reference book. I find it useful since it give full and details explanations with many diagram and picture.
A detailed textbook of molecular biology, explained essential findings and how they were made. For those who want to know the original research of classic knowledge.
