A life form's DNA is the "book" containing all the information needed to manufacture that organism. The DNA is divided into chromosomes (chapters/pages), and each chromosome contains the code for many genes (words/sentences), each made up of several, ordered base pairs (letters/characters).
That's why to say that "DNA is DNA" is exactly equivalent to saying "a book is a book". In either instance, while the statement may be true in the nit-picky sense of "yes, they're made up of the same stuff"...that's the total end of the truth to the statement, as both DNA and books are defined by not the physical medium they're made of, but the stored information within that medium.
