Answer:
D) Alec Jeffreys
Explanation:
Alec Jeffreys, a British geneticist, basically changed the scientific world in 1984. He was working out at the University of Leicester and came up with something groundbreaking – DNA fingerprinting. Now, this isn't about ink and paper; it's about finding unique patterns in our DNA.
Think of it like a genetic ID card. Jeffreys figured out a way to extract DNA from things like blood, semen, or tissues, and then he could match those patterns to specific individuals. This wasn't just a cool trick – it became a game-changer in forensic science. Suddenly, we had a super reliable method to identify people, helping out in crime investigations, paternity tests, and more.
