This video case study explores the approaches scientists used to identify a mutation that causes retinitis pigmentosa (RP), a progressive disease that leads to blindness.
This model shows the skull of Tiktaalik, a vertebrate that existed about 375 million years ago and had features of both fish and tetrapods (four-limbed animals).
This model shows the skeleton of Tiktaalik, a vertebrate that existed about 375 million years ago and had features of both fish and tetrapods (four-limbed animals).
This model shows the pectoral fin bones of Tiktaalik, a vertebrate that existed about 375 million years ago and had features of both fish and tetrapods (four-limbed animals).
This model shows the pelvis of Tiktaalik, a vertebrate that existed about 375 million years ago and had features of both fish and tetrapods (four-limbed animals).
This model shows the humerus bone of Tiktaalik, a vertebrate that existed about 375 million years ago and had features of both fish and tetrapods (four-limbed animals).
This interactive module uses the central dogma as a model for exploring how modern molecular biology technologies can be used to treat different genetic conditions.
This interactive module explores how mutations arise in germline and somatic cells. It also shows how these mutations can lead to genetic conditions, such as cystic fibrosis and cancer.
This interactive module allows students to examine evidence from brain anatomy, tissue histology, and genetic studies to identify possible targets for the treatment of Alzheimer’s disease.
A number of interactive questions are embedded within the short film The Biology of Skin Color, which explores the hypothesis that the variations in skin color in humans arose as adaptations to the intensity of ultraviolet radiation in different parts of the world.
