 Developments in genomics and post-genomics have sparked a number of philosophical questions about molecular biology. Since the genome requires a vast array of other mechanisms to facilitate the generation of a protein product, can DNA really be causally prioritized (see  Section 2.3)?  Similarly, in the face of such interdependent mechanisms involved in transcription, regulation, and expression, can DNA alone be privileged as the bearer of hereditary information, or is information distributed across all such entities and activities (see  Section 2.2)?  And is it appropriate to extrapolate from information about other species’ genomes to how the human genome operates (see  Section 3.3)?
