Correct Answer: Dr. Alec Jeffreys
Solution : The correct option is Dr. Alec Jeffreys.
Sir Alec Jeffreys is well-known for developing DNA fingerprinting, a method of identifying people based on their unique DNA patterns. While researching at the University of Leicester in the United Kingdom, he developed this ground-breaking discovery in 1984. DNA fingerprinting, also known as DNA profiling, has transformed sectors such as forensic science, paternity testing, and criminal investigations. DNA fingerprinting examines and compares certain areas of an individual's DNA known as short tandem repeats (STRs). The quantity of repeating sequences in these areas varies, resulting in a unique pattern for each individual. Scientists can detect whether two DNA samples match or are from different people by analysing these patterns.
