A model of pluripotent vs differentiated cellular gene expression is shown. Pluipotency is found in stem cells that have the ability to become multiple types of cells. Differentiation is the process where a cell becomes specialized and cannot return to its pluripotent state. What explanation best supports the model of pluripotency and differentiation shown above?

A) Differentiated cells have different DNA sequences that pluripotent cells and can produce different protein products.

B) Differentiated cells have fewer gene sequences that pluripotent cells and can only produce limited numbers of proteins.

C) Pluripotent cells recruit molecules from nearby cells to increase gene expression while differentiated cells use only internal transcription factors.

D) Differentiated cells and pluripotent cells have different types of activator or repressor proteins present that positively and negatively regulate gene expression in the cell.
