Introduction:
The molecular and genomic basis of life is at the heart of modern biology. In BIOL 263, we will learn techniques and explore research questions at the forefront of molecular research, focusing on the mechanisms by which the information of the genome is expressed to form the functional molecules of living cells and organisms. The processes of DNA replication, recombination and repair, transcription of RNA from DNA templates, and translation of RNA into protein are discussed in the context of current research, frequently using primary literature. The function of genes and regulation and measurement of gene expression are treated in depth. Students analyze and publish interactive tutorials on the structure and function of key macromolecules. This intermediate-level course presumes a strong background in the basics of protein structure/function, central dogma processes, fundamental molecular techniques for manipulating nucleic acids and proteins, and general chemistry.
Required prerequisites: BIOL 113, 114; one year of chemistry; or permission of the instructor.
Recommended prerequisite or co-requisite: CHEM 231 and 232 (Organic Chemistry).
Reading Materials and Resources:
All reading assignments must be completed before class on the date indicated on syllabus.
Assignments and Grades: Your grade is based on performance in the following areas:
