A continuation of 110. Prerequisite: CHI 110 or permission of the instructor.

A laboratory designed to complement the lecture material in 230. Laboratory and computer projects investigate methods in molecular biology including recombinant DNA, gene cloning and DNA sequencing as well as contemporary bioinformatics, data mining and the display and analysis of complex genome databases. Prerequisite: BIO 230 (should be taken concurrently).

Prerequisite: BIO 230 (should be taken concurrently).

An exploration of genes and genomes that highlights the connections between molecular biology, genetics, cell biology and evolution. Topics include DNA and RNA, and protein structure and function, gene organization, mechanisms and control of gene expression, origins and evolution of molecular mechanisms, and gene networks. The course also deals with the principal experimental and computational tools that have advanced relevant fields, and introduces students to the rapidly expanding databases at the core of contemporary biology.

Laboratory sessions in this course combine observational and experimental protocols both in the lab and in the field. Students gain familiarity with the diverse lineages of life and design and conduct research to address specific hypotheses about a subset of lineages. There are also field trips to local sites where students engage in observations of organisms in their natural habitats and in experimental exploration of ecological interactions. Prerequisite: BIO 154 (normally taken concurrently).

Students in this course investigate the origin, nature and importance of the diversity of life on Earth; key ecological processes and interactions that create and maintain communities and ecosystems; principle threats to the biodiversity; and emerging conservation strategies to protect the elements and processes upon which we depend. Throughout the semester, we emphasize the relevance of diversity and ecological studies in conservation. Laboratory (BIO 155) is recommended but not required.

Laboratory sessions in this course combine observational and experimental protocols. Students examine cellular molecules, monitor enzymatic reactions, photosynthesis and respiration to study cellular function. Students also examine embryology and the process of differentiation, the structure and function of plant systems, and the physiology of certain animal systems.

Prerequisite: BIO 150, (normally taken concurrently)

Students in this course investigate the structure, function and physiology of cells, the properties of biological molecules, information transfer from the level of DNA to cell-cell communication, and cellular energy generation and transfer. The development of multicellular organisms and the physiology of selected organ systems is also explored. In addition to attending lectures, each student participates in discussion sections that focus on data analysis and interpretation while integrating mechanisms across scales. Laboratory (BIO 151) is recommended but not required.

Practical lab experiences in plant propagation, development and physiology, identification and nomenclature of plant parts, identification and treatment of diseases and insect pests, soils, seeds and floral design. The course involves use of the Lyman Conservatory plant collection, field trips and winter/spring observation of outdoor plants. BIO 122 must be taken concurrently. Enrollment limited to 15 per section.
