Groups bonded by only a sigma bond can undergo rotation about that bond with respect to each other. The temporary molecular shapes that result from rotation of groups about single bonds are called conformations of a molecule. each possible structure is called a conformer. An analysis of the ener changes associated with a molecule undergoing rotation about single bonds is called conformational analysis

Primary Structure Sequencing Nucleic Acids核酸序列测定 Chain termination method (dideoxy method), developed by F. Sanger Base-specific chemical cleavage, developed by Maxam and Gilbert Both use autoradiography- X-ray film develops in response to presence of radioactive isotopes in nucleic acid molecules

This chapter will explain the origin of the spontaneity of physical and chemical change. Two simple processes are examined. It shows that a property, the entropy can be defined, measured, and used to discuss spontaneous changes quantitatively. This chapter also introduces a major subsidiary thermodynamic property, the Gibbs energy
