Cells of multicellular organisms contain identical genetic material (the genome) yet can have drastic differences in their structural arrangements and functions. This variation of the distinct cell types comes from the differential expression of genes, which is controlled by interplay between different regulators within the cells, such as transcription factors, the transcription machinery, and the "epigenetic" modifications (which do not change the underlying genetic code) that occur on the DNA and protein factors within chromatin.
