Quizplus · Accepted Answer

The successful cloning of Dolly proved that the nucleus of a fully-differentiated cell can be reprogrammed to be totipotent, meaning it has the ability to give rise to all cell types in the body. This finding was significant because it challenged the prevailing belief that only cells from early developmental stages could be used for cloning.
