The research that led to the creation of this Kit has resolved many questions including: (1) why DNA has a double Helix structure, (a mystery which Nobel Prize recipients James Watson, Francis Crick, and Maurice Wilkins in addition to many others have researched and worked to resolve), (2) how the formation, development and components of the Brain and Body are related to DNA (resolving a 200 plus year old mystery Rene Descartes was working on to determine if the MIND was the BODY, if the BODY was the MIND or Both), (3) how DNA at the molecular level and different Blood Types at the cellular level relate to the Brain, the Body and predisposition to various diseases.
