<unk>  is the process by which the inheritable information in a<unk> , such as the DNA sequence, is made into a functional<unk>  product, such as protein or RNA.
Several steps in the<unk>  process may be modulated, including the transcription step and the post-translational modification of a protein.<unk>  regulation gives the cell control over structure and function, and is the basis for cellular differentiation, morphogenesis and the versatility and adaptability of any organism. <unk>  regulation may also serve as a substrate for evolutionary change, since control of the timing, location, and amount of<unk>  can have a profound effect on the functions (actions) the<unk>  in the organism.
Non-protein coding<unk> s (e.g. rRNA<unk> s, tRNA<unk> s) are not translated into protein.
