All cells perform certain basic functions. Each must selectively transcribe parts of the DNA that makes up its genome into RNAs that specify the structure of proteins. The set of proteins synthesized by a cell in turn determines its structure and behaviour, and enables it to survive and reproduce. So it is crucial that the appropriate stretches of DNA are transcribed in each cell type.
