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 biology, 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 115, 116; one year of chemistry
(Intro or Honors Intro); or permission of the
instructor.
