Abstract
This study aims to establish the significance and impact of using DNA data in forensics. The study employed the anamnestic method, descriptive analysis, and forecasting. The conducted research identified the key problems of creating and using DNA databases, including insufficient logistical and laboratory support, understaffing, lack of special legislation, low level of security, slow filling of databases, disregard of the public position, and the need to establish international cooperation. It was established that DNA analysis enables identifying
the identity of the deceased or a person who cannot identify himself; determining the number of persons at the crime scene; establishing whether DNA traces belong to a suspect; establishing a connection between several crimes by matching DNA samples taken from the scene; establishing those accused of crimes. It is proposed to increase the effectiveness of law enforcement activities through the development of an International Strategy for the Influence of the Use of DNA Databases and ensure international cooperation on the exchange of DNA
information in forensics.

Keywords: DNA databases, DNA analysis, forensic method, crime investigation, human identification, forensic genetic examination.
