What is Gene Expression?
the ability of the cell to precisely activate and deactivate one or more genes in response to a signal.
Gene expression enables a cell to?
enables the cells to activate a gene when it needs protein the gene encodes or needs a higher concentration of the protein & deactivates a gene when it does not need the protein adequate concentration of the protein.
Cell responds to some signals by_______
