Is gene expression the same in both types of cells?

Explanation:

Only a fraction of the genes in a cell are expressed at any one time. The variety of gene expression profiles characteristic of different cell types arise because these cells have distinct sets of transcription regulators. Some regulatory proteins affect the transcription of multiple genes.
