For example, if a large group of people with a given diagnosis have several SNPs in common, but not healthy people, then mutations may be looked for within those SNPs. One type of theoretical biochip is a small device constructed of large organic molecules, such as proteins, and capable of performing the functions (data storage, processing) of an electronic computer. A mutant site (T93G) in uidA gene. First, in 1983 Kary Mullis invented the polymerase chain reaction (PCR) technique, a method for amplifying DNA concentration. Microfluidics are compared for ease/efficiency Incorporation of suitablesensing modality by evaluating the great gatsbyrhetorical essay tradeoffs and downselect detection modes(color / luminometric, electrochemical, biochemical, optical methods) forspecific need.
