1 DNA contains four basic building blocks or â bases â: adenine (A), cytosine (C), guanine (G) and thymine (T). 2  The order, or sequence, of these bases form the instructions in the genome. 3  DNA is a two-stranded molecule. The bases always pair together in the same way, A with T, C with G. 2  Each base pair is joined together by hydrogen bonds. 3  Each strand of DNA has a beginning and an end, called 5â (five prime) and 3â (three prime) respectively.
Many believe that genome-based medicine, frequently called personalized medicine, is the future of healthcareâthe next logical step in a world in which more is known about human genetics, disease, and wellness than ever before.
These issues, as well as the difference between Personalized Medicine and Precision Medicine, revolve around the fact that Personalized and Precision Medicine are presented as arising naturally from the intersection of âomicsâ technologies and Big Data algorithms.
