An Experiment-based Methodology for Classical Genetics and Molecular Biology

This paper proposes an experiment-based methodology for both classical genetics and molecular biology by integrating Lindley Darden’s mechanism-centered approach and C. Kenneth Waters’s phenomenon-centered approach. We argue that the methodology basing on experiments offers a satisfactory account of the development of the two biological disciplines. The methodology considers discovery of new mechanisms, investigation of new phenomena, and construction of new theories together, in which experiments play a central role. Experimentation connects the three type of conduct, which work as both ends and means, occurring in a circular way and constituting an overall process of scientific practice from classical genetics to molecular biology.
