   And a follow-up.

   From Mike's first article:
   

   The fact that DNA exists as a double helix of two nucleotide chains foreshadows the manner in which the structure of DNA is perfectly suited for replication. To replicate DNA, all you need to do is unwind the two strands and then use each strand as a template for the synthesis of a new, complementary strand. In one molecule, there are two perfect solutions for two design problems"”coding the machinery of life and perpetuating the information across time. A more beautiful molecular expression of the form-function relationship would be hard to imagine. Seen from this vantage point, the very structure of DNA is evidence that indicates life was designed to reproduce. (which is reprinted from his book)

   And from the second article:
   

   Why think it is merely a coincidence that the alpha helix diameter and the width of the major groove are the same? On the contary, it simply enhances and extends the inheret rationality and complementarity that lies behind these two crucial biological molecules "“ a match made in heaven.
