This is a qualitative research paper that used the content analysis method. Thirty-one sources which include journal articles, credible websites, and books were used to discuss the importance of having national and global genetic databases. DNA phenotyping is the technology used in criminal justice to identify crime suspects through observable traits in their DNA. This can play a key role in convicting the right crime perpetrators and avoiding future court appeals. It also helps during disaster recovery, where the victims are identified based on their DNA samples. Law enforcement agencies frequently use DNA to identify victims and solve high-profile cases such as murder. However, despite its success and usefulness in criminal justice, it faces some challenges. For example, there are often legislation limitations concerning access to and use of DNA evidence. In some countries, it is limited and can only be used for specific crimes; in others, it is widely used, but its use is limited in other ways, such as restrictions as evidence in court. It also faces ethical issues such as intentionally planting DNA samples or leaking sensitive information. Also, the public needs to fully support its use, even for low-profile cases. Despite these limitations, a universal DNA database would help reduce investigation costs and improve their effectiveness, sometimes even for property crimes. DNA is extremely useful due to its ability to solve complicated identity problems. An exemplary DNA database should contain DNA profiles for all citizens. Increasing the capacity of current databases, and connecting them to share information with authorized officials will help to create a robust DNA database for future generations.
