Culmination of molecular genomic techniques in forensic crime investigation

The advancements in the sectors of forensic science along with biological sciences has proved to be a cornerstone in serving justice to people across the world. Genes are the coding languages that the body uses to define the definite characteristics of a human being that differentiates that being amongst million others. Now, to distinguish and get hands on the criminals, unique techniques are developed and introduced in the market to be implemented in the real world in order to handout proper verdict by the judicial system. This paper deals with few of those molecular biology techniques that are implemented in forensics to unfold the reality of the cases. The paper discusses the basics, principles, pros, and cons along with the future aspects of the techniques with the reader and aims at clarifying the concept of analysis of the DNA. Techniques such as PCR, STR, mtDNA, NGS along with forensic DNA database CODIS are analysed in the paper which showcase the importance of the presence of a technique with a database for an optimal inference of the results.
