How does gene expression allow humans to adapt to changing internal and external conditions support your answer with an

t your answer with an example.

regulators, then the expression of these regulators must also depend on the expression of other regulators, and their expression must depend on the expression of still other regulators, and so on. Cells would therefore need an infinite number of genes, most of which would code for transcription regulators.” How does the cell get by without having to achieve the impossible?
