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).

This video follows biologist Elinor Karlsson, who studies dogs to find genes associated with traits, including certain diseases.

This animation shows how mutations in an ion channel protein lead to the genetic disease cystic fibrosis. The animation also discusses how research on this protein has been used to develop treatments for the disease.

This animation describes how skin color is generated by skin cells as protection against ultraviolet (UV) radiation.

This film explores the genetic and archaeological evidence that suggest that corn is the result of the domestication of a wild Mexican grass called teosinte.

This animation explores how carbon enters the atmosphere and can be removed through a series of chemical reactions.

This animation shows how varying concentrations of a signaling molecule activate different transcription factors to determine cell fate.

This animation shows how HIV infects a cell and replicates itself using reverse transcriptase.

This animation shows how stem cells from early mammalian embryos can be grown and studied in a laboratory.

This animation describes the formation and fates of the three germ layers in a human embryo.

This animation shows how salamanders can replace missing limb tissues with the help of cells similar to stem cells.

This video explores how people developed the different breeds of dogs that exist today through selective breeding.
