DNA has been referred to as the “mystery substance” that impacts who you are (in comparison to your biological relatives). Scientists at the University of Washington believe they have discovered that DNA is really an incredibly powerful information storage device and much more complex than originally believed. In fact, they believe it contains a second hidden code. The genetic code uses a 64-letter alphabet called codons. Some codons, “duons,” can have two meanings, one related to protein sequence, and one related to gene control. This means that “many DNA changes that appear to alter protein sequences may actually cause disease by disrupting gene control programs or even both mechanisms simultaneously,” according to a researcher. It appears that a secret language in the DNA itself may be a contributor to how "nature" is expressed. Sounds a bit like Dan Brown’s Da Vinci Code! No wonder every individual, every brain, is unique.
