The cell is the basic unit of life, and all living organisms are composed of one or more cells. Cells contain genetic material and essential components responsible for growth and vital functions. In forensic science, the cell forms the scientific foundation for analyzing biological evidence and linking suspects to crime scenes. Cells and Biological Evidence Biological forensic evidence includes samples that contain cells such as: • Blood • Saliva • Semen • Skin • Hair These samples are analyzed to obtain cellular and genetic information that aids in personal identification. DNA Within the Cell Deoxyribonucleic acid (DNA), located inside the cell nucleus, is the most important component in forensic investigations. DNA carries unique genetic information for each individual. Through DNA analysis, forensic scientists can: • Identify suspects • Link individuals to crime scenes • Exonerate innocent people with high accuracy ⸻ Cells and Determination of Injury or Death Cellular examination helps in: • Detecting cellular damage caused by trauma or burns • Distinguishing injuries that occurred before or after death • Identifying pathological or toxic cellular changes This information contributes to understanding the circumstances of a crime. Importance of Cell Biology in Forensic Science Cell biology provides a fundamental scientific basis for forensic science, connecting biological knowledge with legal applications and supporting justice through precise evidence analysis. Conclusion Cells play a central role in forensic science as the primary source of biological and genetic information. This highlights the importance of cell biology in crime investigation and the pursuit of justice. Al-Mustaqbal University – the first university in Iraq.
