BIOL_SCI 101.6: First Year Seminar - Wonders of Biology 

At the molecular level, life is a chemical engine so complex that it makes everything humans have invented and built look like child play. Through a mix of lectures, workshops and writing assignments, the seminar will explore some of the wonders that are at the core of biological systems. The goal is to inspire you, and to illustrate how studying biology yields insights that are mirrored in seemingly unrelated things like social media, architecture, airline route design, computer sciences, or sociology to name but a few.

Registration requirement: First years only.

BIOL_SCI 201: Molecular Biology

Students will learn about the basics of molecular biology, including the structure of macromolecules, DNA replication, transcription, and translation and the mechanisms by which these processes are regulated. Students will also learn current biotechnology methods used to study molecular biology.

Credit not allowed for both BIOL_SCI 201-0 and BIOL_SCI 215-0

BIOL_SCI 234: Investigative Laboratory

This course is the culminating life-science lab experience in the sophomore-year series. Students design and generate reagents that can be used in larger experiments. The topic varies from year to year, but typically revolves around the sub-cloning of a specific gene fused to a reporter for detection.

Prerequisite: BIOL_SCI 233-0.

BIOL_SCI 301: Biochemistry

This class is an introductory level biochemistry course. It covers basic topics such as macromolecular structure and function of biologically relevant macromolecules (proteins, carbohydrates, nucleic acids, lipids), membrane structure, membrane transport, signal transduction, chemical logic in metabolic transformations, and carbohydrate metabolism. The course strongly emphasizes conceptual understanding, and offers extensive student-teacher interaction. Active participation in all course elements is encouraged and advantageous as students are expected to move past memorization of facts to a fully interconnected and integrated understanding that allows students to apply their knowledge to solve complex problems. This course will equip students preparing for the MCAT and upper level biology courses. Wednesday discussion section meetings will be for quizzes/midterms.

Quizzes (20-30 minutes) are held during the Wednesday 7-9pm discussion section for Biol_Sci 301. 
If another class conflicts with a Biol_Sci 301 exams, we do not offer an alternate time.

BIOL_SCI 333: Plant Animal Interactions

Plant-animal interactions (BIO SCI 333/PBC 410). This course will explore the ecology of plant-animal interactions. Through the survey of the scientific literature, we will investigate the consequences of mutualistic interactions (pollination and seed dispersal) and antagonistic interactions (herbivory and parasitism) for individual organisms, population dynamics, ecological communities, and entire ecosystems. Finally, we will learn how these various interactions are responding to global change, including habitat destruction and climate change. 

Prerequisite: The former BIOL_SCI 330-0, BIOL_SCI 339-0, or ENVR_SCI 202-0.

BIOL_SCI 336: Spring Flora

Spring Flora merges aspects of plant evolution and identification (with an emphasis on learning about the local flora) with plant ecology (with an emphasis on ecological interactions and adaptations). This course takes a field-based approach to learning the process of identifying major components of the local flora. Understanding vegetative and reproductive structures of plants, and use of this knowledge to identify plants with taxonomic keys will be emphasized. Ecological interactions, adaptations, and related conservation issues will also be discussed. The lecture portion of the course will take place on the Evanston campus on Mondays. On Wednesdays, the field component will take place at the Chicago Botanic Garden. The instructor will reach out to all enrolled students ahead of time to organize transportation options (transportation will be made available to those who need it. Note that the time scheduled for the course DOES NOT INCLUDE transportation time, so 30-45 minutes should be budgeted before and after class on Wednesday for transportation.

BIOL_SCI 341: Population Genetics

 Change in the genetic composition of populations over time is the basis of evolution. The field of population genetics describes this genetic change, both as replacement of genes within populations, and as diversification among populations which can become species. This course reviews the dynamics of genetic variation in populations through evidence from natural history, experimentation, and theory. Topics include: natural selection, genetic drift, inbreeding, mutation, and geographic structure of populations, based on single-locus models, molecular sequences, and quantitative traits. More specialized topics such as sexual selection, kin and group selection, and the evolution of sexual reproduction and recombination will be included as time allows.
