What important lesson for the mechanisms of development can we derive from the ability to clone frogs by nuclear transfer?

#Unit 5. Developmental Biology
  1. that the selective gene expression seen in differentiated cells does not result from an irreversible loss of genes, or their potential for expression
  2. that a piece of a frog can be "planted" to obtain a new, cloned individual, just like in plants
  3. that the pattern of gene expression in a differentiated cell can only be reversed if the nucleus is removed from the cell
  4. that the mechanisms of development are irreversible in all organisms except frogs
