50 years to write the book of life - now we can start to read the text

Article Abstract:

An examination of the breakthroughs that have flowed in the 50 years since the structure of DNA was discovered. It is argued that for the first three decades following the discovery of DNA's structure in 1953, there was no discernable impact of this discovery on anything remotely relevant to the practice of medicine, and it is only since the early-1970s that methodological advances come far together to enable the medical promises of DNA.

A chip off Mother Nature's own hard drive
