The black-footed ferret (Mustela nigripes) is one of North America's most endangered mammals. In 2020, scientists successfully cloned a female named Elizabeth Ann using preserved frozen tissue from a donor ferret that died in 1981. This was achieved using somatic cell nuclear transfer (SCNT) with a domestic ferret acting as both the egg donor and the surrogate mother.
Describe the process of somatic cell nuclear transfer (SCNT) that was used to produce Elizabeth Ann.
