The topic of DNA-structure is important both for me personally and society in general. One of the most useful ways of implying the DNA-structure to the modern world can be found in the field of forensic science. Adenine (A), guanine (G), cytosine (C), and thymine (T) are the four chemical bases that make up the code that stores the information in DNA (Saladin, 2020). Similar to how the letters of the alphabet occur in a specific order to form words and sentences or sequence, of these bases dictates the information accessible for creating and maintaining an organism.
The characterization of DNA has been used in forensic science for criminal investigation. The developments of aspects of molecular genetics have made it possible in identifying the differences in parts of the DNA from person to person. It is the differences that have been used in the forensic application. The DNA typing is critical for personal identification, and it plays a role in determining the individuals that may be involved in a crime (Allwood et al., 2020). The process has been crucial in ensuring efficiency in forensic science since it provides enough evidence on the identification of a criminal.
One of the areas that DNA in forensic science can be used is in rape cases. The DNA of the rapist can be identified by acquiring it from the body of the victim. It helps in determining the individual involved in the act. Additionally, DNA typing could be used in cases of robbery with violence. The fingerprints the criminals leave on the surface of areas they have robbed play a vital role in identifying the offender. Thirdly, DNA could be used in homicide cases in determining the identity of the killers. It is through the matching of the DNA collected from the scene of the crime with that of the suspect that helps in determining the murderers (Sinha et al., 2020). Hence, the DNA-structure is an important piece of knowledge that helped solve numerous criminal cases.
