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.
Personalized medicine is the use of detailed information about a patient's genotype or level of gene expression and a patient's clinical data in order to select a medication, therapy or preventative measure that is particularly suited to that patient at the time of administration.
Not to be confused with Designer drug. Drug design, sometimes referred to as rational drug design or simply rational design, is the inventive process of finding new medications based on the knowledge of a biological target.rug design frequently but not necessarily relies on computer modeling techniques. This type of modeling is often referred to as computer-aided drug design. Finally, drug design that relies on the knowledge of the three-dimensional structure of the biomolecular target is known as structure-based drug design.
