Which option is NOT one of the two main DNA types commonly referenced in forensic analysis?

• A. Nuclear DNA
• B. Mitochondrial DNA
• C. Insect DNA
• D. None of the above

Answer: (C)

In forensic analysis, two main DNA types are used for human identification: nuclear DNA and mitochondrial DNA. Nuclear DNA comes from the cell’s nucleus and provides many markers (STRs) that can distinguish individuals with high precision. Mitochondrial DNA, found in mitochondria, is inherited from the mother and exists in many copies per cell, making it especially useful when samples are degraded or scarce. Insect DNA, while studied in forensic entomology for timeline estimates and other clues, is not one of the two primary DNA types referenced for human identification. Therefore, insect DNA is not among the main categories relied upon in standard forensic DNA analysis.
