#Unit 3. Fundamental Processes

Promoters that are constitutively expressed and needed in all cells (their genes are sometimes called housekeeping genes) have upstream sequence elements that are recognized by ubiquitous activators.

#Unit 3. Fundamental Processes

Proteins bound at enhancer elements interact with proteins bound at promoter elements via DNA looping, very often through intermediates called coactivators.
