In this phenomenon-driven activity, students investigate how cells are signaled to make melanin and explain how mutations in melanin pathway proteins affect the coat color of various organisms.
This video follows germplasm bank coordinator Cristian Zavala Espinosa and geneticist Sarah Hearne, who are part of the global effort to preserve the genetic diversity of maize (corn).
In this inquiry-based activity, students engage in science practices to figure out why some people with a genetic condition that usually leads to sickle cell disease do not have disease symptoms.
In this activity, students engage with an example from the Serengeti ecosystem to illustrate the exchange of nutrients between plants, animals, and the environment.
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.
This activity guides the analysis of a published scientific figure from a study that used SNP genotyping to identify the mutations that result in morphological differences in stickleback fish.
This activity guides the analysis of a published scientific figure from a study that investigated how random mutations during cell division can contribute to cancer.
This multipart activity is designed to give students a firm understanding of genetic profiling using short tandem repeats (STRs), which is a process used by forensics labs around the world.
This activity guides the analysis of a published scientific figure from a study that explored how dinosaurs may have regulated their body temperatures.
This activity guides the analysis of a published scientific figure from a study involving illegal elephant poaching. In this study, scientists used DNA profiling to determine where ivory seized from poachers had originated.
