Browsing Stepping Stones to Biology
A molecular approach to biology must develop in students an
understanding of molecules, their interactions and the consequences of
these interactions. Biological phenomenon now more than ever rely on
chemical and physical principles for molecular explanations of the
phenomenon. We have selected 10 physical-chemical principles that underlie many biological processes: we call them "Molecular Stepping Stones." Below are links to entry level model-based activities for the Stepping Stones.
