Forensic DNA Analysis

DNA (Deoxyribonucleic acid), sometimes called the base or genetic blueprint, was first described by scientists Francis H.C Crick and James D. Watson in 1953 and established the role of DNA as the building block of the genetic code of living things. DNA is the same in every cell throughout the human body, be it a skin cell, a sperm cell, or a blood cell. Except for identical twins, no two people have the same DNA pattern. Among the many new tools that science has provided to analyze the evidence for the experimental evidence, the powerful and controversial analysis of deoxyribonucleic acid, or DNA, is what makes up the genetic code of many living things. DNA analysis, also known as DNA typing or DNA profiling, examines DNA based on tangible evidence such as blood, hair, and sperm, and determines whether it can be compared to DNA taken from certain individuals. DNA analysis has become a common method of evidence in criminal prosecutions. It is also used in civil courts, especially in cases involving the patent of Paternity of Identity.

There are various evidence that we can see here. Here blood is present, bones are present, viscera samples are present, biological fluid are present. From all of these, we can extract DNA for identification of the individual. DNA extraction is a reasonably common operation used in biological academic and research contexts. In a forensic DNA setting, DNA extraction is the critical initial step toward the development of DNA profiles used to support criminal justice system convictions or exonerations.
