DNA testing plays an important role in research. It forms a core basis of other fields such as medicine, agriculture, genealogy, forensic science and more. The word 'DNA' stands for deoxyribonucleic acid. DNA is essential to the proper functioning of human cells. In fact, DNA is actually referred to as the blueprint or the foundation which holds the information required for encoding the proteins and other cell components. The importance of DNA testing can be understood from research, medical and judicial perspectives. Below is some of the information that will explain the importance of DNA testing.
The result of a DNA test uniquely identifies an individual. As a result, there are many criminal cases that can be solved by placing the subject at the crime scene. First, forensic investigators get samples of blood, hair or tissue from the crime science. Secondly, laboratory technicians can easily verify the identity of the person who is involved in the crime. When presented in a court of law, the result of a DNA test is generally accepted as a fact. From that result, the judiciary and police system will rely on the credibility and power of DNA fingerprinting to obtain a verdict.
In agriculture, the use of DNA testing is also important. It is used as a tool to modify important varieties of crops. The genetic modification of crop varieties are carried out to make them more resistant to diseases and also to increase the crop yields. Not only that, the plant grows better, produce more yield or have better innate resistance to insects, etc. DNA testing and research is also used to improve the animal breeds. Because of this genetic technique, there is more production of plants variety.
Aside from the above application of DNA in some fields, here are some of the uses of DNA and why it is very important especially for human beings:
DNA is one important components of life. The paternity test serves as the basis of important information about human beings.
