Biology is the study of living organisms. Biology includes many sub-disciplines, such as microbiology and biochemistry. Microbiology studies microorganisms, while biochemistry studies the building blocks that compose organisms. Although distinct areas of biology, the two share many attributes. The aims of biochemical and molecular biological research are complex and diverse. Investigation of the network of chemical reactions taking place in living organisms and representing the most fundamental phenomena of life, identification of the molecules playing roles in biochemical processes, determination of their structure, function and interactions, examination of the molecular background of metabolism, the flow of energy and information within organisms are all among the common goals of biochemists and molecular biologists. The present book uniquely integrates the theory and practice of key experimental techniques for bioscience graduates.
