Welte explains that the production of certain proteins takes place along a type of assembly line that carries raw materials from the nucleus to the posterior end of the egg cell, where these proteins are then manufactured.

In the initial work at the Roslin Institute, the egg cells along with their transplanted nuclei were then implanted directly into a foster mother, where they developed and, in the case of Dolly, resulted in a viable offspring.
