This 13-minute video shows students both the scientific and cultural context surrounding Dolly, the world’s first clone of an adult mammal. The video clarifies the scientific process that led to Dolly’s creation, explores how media and political leaders responded to the birth with surprise and fear, and how Dolly influenced the ongoing debate over the use of human embryos in stem cell research. Useful for lessons focused on gene expression or biotechnology, the video can be used to initiate discussion or debate about bioethics and epigenetics.
