Q.

If the nucleus from another amoeba is transplanted to enucleated amoeba, the recipient survives and divides and while the donor amoeba (enucleated) dies. This experiment shows that

1. Mitochondria are essential for normal life

2. Amoeba does not require any organelle for its survival

3. Ribosomes are essential for normal life

4. The nucleus is essential for normal life
