In eukaryotes, what is the difference between promoter proximal elements in "housekeeping genes" vs. cell-specific genes, and how does this relate to gene expression?
What will be an ideal response?
In genes that are expressed in all cell types for basic cellular functions ("housekeeping genes"), promoter proximal elements are recognized by regulatory activator proteins that are ubiquitous to all cell types. In cell-specific genes, the proximal elements are recognized by activators that are found only in those cells.
