DNA fingerprinting was founded by:
**Core Concept**
DNA fingerprinting is a forensic technique used to identify individuals based on their unique DNA profiles. This method involves analyzing specific regions of the genome, typically short tandem repeats (STRs), to generate a unique pattern of DNA fragments.
**Why the Correct Answer is Right**
Alec Jeffreys, a British geneticist, is credited with the discovery of DNA fingerprinting in 1984. He developed this technique by analyzing DNA samples from families and identifying unique patterns of DNA fragments. The process involves restriction enzyme digestion, gel electrophoresis, and autoradiography to visualize the DNA fragments. This technique has since become a crucial tool in forensic science for identifying individuals, solving crimes, and establishing paternity.
**Why Each Wrong Option is Incorrect**
**Option A:** The discovery of DNA fingerprinting is often attributed to the work of several scientists, but Alec Jeffreys is widely recognized as the founder of this technique.
**Option B:** While DNA sequencing is a related field, it is not the same as DNA fingerprinting, which focuses on identifying specific DNA patterns rather than sequencing the entire genome.
**Option C:** DNA microarrays are a tool used in genomics to analyze gene expression, but they are not directly related to the discovery of DNA fingerprinting.
**Clinical Pearl / High-Yield Fact**
Alec Jeffreys' discovery of DNA fingerprinting has had a significant impact on forensic science, allowing for the identification of individuals and the solving of crimes that were previously unsolvable.
**Correct Answer: C. Alec Jeffreys**
