Since DNA contains genetic code, much of it is studied and analyzed for a variety of reasons. Generally, DNA testing may be used in identification or classification of family trees and it may also be used in various sciences for study in diseases and crimes. In cases where a particular child has no identified father, DNA testing is a big help in tracing the real person who fathered the said child.
Genetic modification involves insertion of foreign DNA into the nucleus of a normal cell where it integrates with the host DNA. Genetic analysis uses molecular techniques to detect the inserted transgenic DNA (GMO) in a sample. The method most commonly used for this purpose is PCR (Polymerase Chain Reaction). The PCR technique amplifies (copies) the DNA billions of times in order for detection and quantitation to be possible.
