Microbes inhabit the world's oceans, deserts, lakes, soils, and atmosphere, and play a vital role in the Earth's biogeochemical cycles. As humans, we harbor a diverse microbial flora estimated to outnumber our own human cells. During this course, we will explore this microbial world by investigating the structure, physiology, genetics, and evolution of microorganisms with a focus on bacteria, but including discussions of archaea, viruses, and microbial eukaryotes.
(Offered as BIOL 251 and BCBP 281) A study of the molecular mechanisms underlying the transmission and expression of genes. DNA replication and recombination, RNA synthesis and processing, and protein synthesis and modification will be examined. Both prokaryotic and eukaryotic systems will be analyzed, with an emphasis upon the regulation of gene expression. Application of modern molecular methods to biomedical and agricultural problems will also be considered. The laboratory component will focus upon recombinant DNA methodology.
(Offered as BIOL 230 and ENST 210.) A study of the relationships of plants and animals (including humans) to each other and to their environment. We'll start by considering the decisions an individual makes in its daily life concerning its use of resources, such as what to eat and where to live, and whether to defend such resources. We'll then move on to populations of individuals, and investigate species population growth, limits to population growth, and why some species are so successful as to become pests whereas others are on the road to extinction.
In their diverse forms, plants play the role of sustaining life on Earth. Plants are also tractable research models, which have facilitated many scientific discoveries and illustrate different approaches to studying organismal biology. This course will strongly integrate lecture, laboratory and field-based material to address plant biology as a foundational discipline in the life sciences. We will include studies on the structures and adaptations that reflect diverse life histories and ecologies, with experimental exercises and work in natural populations.
