Describes the nature and capabilities of methods used to characterize protein and peptide structure, indicating that they have undergone changes which have improved the speed, reliability, and applicability of the process. Also indicates that high-performance liquid chromatography and gel electrophoresis have made purifying proteins and peptides a…

Described is the basic biology involved in mapping chromosomes as presented at a symposium at a recent meeting of the American Chemical Association which focused on the Human Genome Initiative. Different types of gene maps and techniques used to produce gene maps are discussed. (CW)

Discussed are some of the strategies required to try to detect and explain DNA markers that account for small amounts of behavioral variation. Situations in both animal and human behavior are described. The link between molecular biology and behavior is highlighted. (CW)

Discusses a symposium which focused on the influence of inorganic chemistry on organic synthesis, the impact of organic chemistry on biochemistry and vice versa, chemical reaction dynamics, and advances in inorganic chemistry. Explains the purpose of the symposium was to illustrate the intellectual dynamism of modern chemistry. (MVL)
