This interactive module consists of a virtual Winogradsky column, which can be used to explore the diversity of microbes, microbial metabolic strategies, and geochemical gradients found in sediments.
Several questions are embedded within the short film The Making of the Fittest: Got Lactase? The Co-evolution of Genes and Culture, which explores the genetics of lactase persistence and evolution of the trait in some human populations.
This interactive module explores the phases, checkpoints, and protein regulators of the cell cycle. The module also shows how mutations in genes that encode cell cycle regulators can lead to the development of cancer.
This interactive, modular lab explores how stickleback fish and fossil specimens are used to study evolutionary processes, with an emphasis on data collection and analysis.
This tutorial describes how bacteria communicate by a process known as quorum sensing, as shown through a series of experiments involving genetically engineered bioluminescent bacteria.
