Study Notes
Forensic Analysis of Physiological Fluids and DNA
- Blood, semen, saliva, urine, and other biological fluids are commonly encountered in crimes of assault, homicide, and sexual assault.
- Methods of analysis for blood are well developed for forensic purposes, while methods for other biological fluids vary in sophistication.
- Morphological characteristics and DNA analysis, including nuclear and mitochondrial DNA, are used for unequivocal identification of physiological fluids.
- Polymorphisms in proteins, nucleic acids, and polysaccharides contribute to the uniqueness of individuals and their biological materials.
- Secretor status, controlled genetically, affects the presence of ABO agglutinogens in body fluids, with around 80% of the population classified as secretors.
- Secretor status is correlated with another cellular antigen system known as the Lewis system, impacting the analysis of mixed stains in sexual assault cases.
- DNA analysis can link a suspect to a crime scene or victim, with sensitivity, specificity, and controls being crucial for accurate interpretation.
- Common sources of DNA at crime scenes include blood, semen, saliva, urine, hair, teeth, bone, and tissue, as well as pattern evidence like fingerprints.
- Biological evidence can easily be contaminated or destroyed, emphasizing the importance of proper collection and handling protocols.
- Forensic DNA analysis seeks to identify the source of biological evidence and may employ techniques such as electrophoresis, ELISA, and DNA/RNA typing.
- Identical twins cannot be distinguished using current forensic DNA STR typing methods, but epigenomics may offer a potential solution for differentiation.
- Every human being is biologically unique due to the different sequences of DNA in their chromosomes, allowing for individualization based on DNA.
