DNA reader

[iLL]

I'm just curious... According to wiki, "DNA is often compared to a set of blueprints, since it contains the instructions needed to construct other components of cells, such as proteins and RNA molecules."

DNA being “blueprints” implies that something knows how to read these blueprints. What's reading the blueprints, and how does it know how to read the blueprints?

Thats a good question. Maybe this link will help.
