The Evolution of Molecular Biology
The Search for the Secrets of Life
- Expands on the development of molecular biology from the convergence of two independent disciplines, biochemistry and genetics
- Discusses the value of molecular biology in a variety of applications
- Includes research ethics and the societal implications of research
- Emphasizes the human aspects of research and the consequences of such advances to society
Researchers, academics, and students in life sciences, for example in molecular biology, evolutionary biology, biochemistry, genetics/molecular genetics, epidemiology, oncology, gerontology, cell biology, and microbiology, as well as many disciplines beyond biological science; secondarily, as an auxiliary text for specific courses and seminars at colleges and universities
