The study of DNA and genetics is one area of science which is not only theoretically fascinating but also practicable useful in many ways. One of the main applications of the growing understanding of DNA and the role that human genes play in people's lives is various forms of DNA genetic testing. This is a process which has a wide variety of applications and each of them is useful to people in different ways. We'll now take a look at various forms of DNA genetic testing and what they are used for.
One area of genetic testing which is commonly undertaken is that relating to genetic diseases. It is possible to carry out DNA genetic testing on an adult human in order to determine if they have genes in their makeup which will lead to a serious illness or adverse health condition later in their life. This is possible to detect before the disease shows any symptoms whatever. A huge advantage of this form of early testing is the extra time both the patient and the doctor have to put into place preventive and coping methods which can help a person navigate the challenges of their health and live as fuller life as possible.
Another use for this type of testing is to screen foetuses in the womb to make sure they are developing correctly and have no genetic abnormalities. Some of the conditions which can be detected by foetal DNA genetic testing include Down syndrome. The parents of a fool that has tested positive for some form of DNA genetic disorder have a range of options. They may wish to terminate the pregnancy in order to spare the child from living a life of illness. Alternately, they may wish to keep the child and knowing about their condition early on gives both parents a lot of time to prepare and adjust in preparation for dealing with an abnormal child.
Law enforcement is another area of life which has seen a lot of benefit from the advances in DNA genetic testing. Using high-tech methods a law enforcement department is able to perform DNA genetic analysis on a crime scene to gain clues about a criminal's identity. For example, they might find a gene which indicates the criminal has a certain physical attribute. This material can be compared with the DNA genetic data imposed on law enforcement databases and this could link known criminals to new crimes.
