Study Notes
DNA Profiling Development
- Sir Alec Jeffreys independently developed a process for DNA profiling in 1985, making it a breakthrough in forensic science.
Definition of DNA Profiling
- DNA profiling, also known as DNA typing or DNA fingerprinting, is a method used to identify an individual’s unique DNA characteristics.
Applications of DNA Profiling
- Widely used in forensic science for crime scene investigations to identify suspects.
- Utilized in paternity testing to establish biological relationships.
- Applied in immigration and ancestry testing for verifying genealogical connections.
- Involved in medical diagnostics for detecting genetic disorders.
Advances in DNA Identification
- Scientific advances in the late 20th century, particularly the discovery of the polymerase chain reaction (PCR) in the 1980s, enabled the use of DNA for individual identification.
DNA Barcoding
- DNA barcoding is a technique used for species identification using a short genetic sequence from a standardized region of the genome, useful in biodiversity studies and conservation efforts.
