DNA Profiling: Applications, Procedures, and Ethical Considerations
Overview
This paper examines DNA profiling as a method for individual identification and analysis of unique DNA patterns from body tissue samples. It explores multiple applications including paternity testing, criminal investigation, disaster victim identification, and organ transplant compatibility, while addressing both the benefits and limitations of the technology including contamination risks and privacy concerns.

Question 1
Determining an individual's identification by extracting and analyzing their sample of body tissue's unique DNA pattern is DNA profiling. DNA profiling can also determine the identities of a person's relatives and other family members. The first thing that needs to be done is to establish a person's identity and the relationships between them and their immediate family members and other relatives (MyHeritage, 2021). When a relationship needs to be proven, such as in immigration or paternity concerns, having documentation like this may be helpful. Second, it plays a role in determining whether or not an individual is a potential perpetrator. DNA evidence discovered at a crime scene or in the victim's sperm, in the case of a rape victim, can be used to identify a suspect positively (St. John, 2020). Thirdly, it can be used to identify those affected by natural disasters. Natural calamities such as tsunamis, earthquakes, and fires can render a person's physical body unrecognizable; however, DNA profiling may still assist in identifying them even under these circumstances (Wilson-Wilde et al., 2013). The procedure for the transplant is in its fourth stage. Completing a DNA compatibility test between the recipient of an organ transplant and the organ donor makes it feasible to decrease the probability that the transplanted organ will be rejected.
