First successful nuclear transfer (1 gen 1952 anni – 31 dic 1952 anni)

Descrizione:

Briggs and King transferred the nucleus from an early tadpole embryo into an enucleated frog egg (a frog egg from which the nucleus had been removed). The resulting cell developed into a tadpole. This experiment showed that the nucleus directs cell growth and, ultimately, an organism’s development and that embryonic cells early in development are better for cloning than cells at later stages.
