BIOL UN2501x or y Contemporary biology laboratory
3 pts. Professor Hazen.
Strongly recommended prerequisite or corequisite: BIOL UN2005 or UN2401. Experiments focus on genetics and molecular biology, with an emphasis on data analysis and experimental techniques. The class also includes a study of mammalian anatomy and histology. Each section is limited to 28 students. Lab fee: $150.

BIOC UN3501 Biochemistry: structure and metabolism
4 pts. Professors Stockwell.
Prerequisites: BIOL UN2001 or UN2005 and one year of organic chemistry. Lecture and recitation. Students wishing to cover the full range of modern biochemistry should take both BIOC UN3501 and UN3512. UN3501 covers subject matters in modern biochemistry, including chemical biology and structural biology, discussing the structure and function of both proteins and small molecules in biological systems. Proteins are the primary class of biological macromolecules and serve to carry out most cellular functions. Small organic molecules function in energy production and creating building blocks for the components of cells and can also be used to perturb the functions of proteins directly. The first half of the course covers protein structure, enzyme kinetics and enzyme mechanism. The second half of the course explores how small molecules are used endogenously by living systems in metabolic and catabolic pathways; this part of the course focuses on mechanistic organic chemistry involved in metabolic pathways.
